taylanbakircioglu 02b1cb2bca feat: v1.5.0 — Site Wizard (Issue #14) + ACME Diagnostic Panel (Issue #13) 
Closes #13, Closes #14.

This release squashes the v1.4.0 → v1.5.0 development line. v1.4.0
shipped the ACME stability & enterprise audit (Issues #10/#11/#12).
v1.5.0 builds on that foundation with two co-equal headline features
plus a 22-round audit campaign hardening the prior configuration
surface. License remains MIT for v1.5.0 (relicense to AGPL-3.0
lands in v1.5.2).

------------------------------------------------------------------
HEADLINE FEATURE A — ACME Diagnostic Panel (Issue #13)
------------------------------------------------------------------
A live pre-flight + post-failure diagnostic surface for every ACME
order, reachable from the ACME Automation page. The panel exists
to make ACME failures legible to operators who do NOT have shell
access to the API host.

Endpoints (`backend/routers/acme_diagnostics.py`):
  POST /api/letsencrypt/orders/{order_id}/diagnostics
       Run the full 5-check suite (DNS / port-80 / routing /
       account / agents) and humanize the order's `error_detail`
       (>=11 RFC-8555 problem types, backwards compatible with
       legacy plain-string failures).
  POST /api/letsencrypt/orders/{order_id}/diagnostics/
                                {check_id}/rerun
       Re-run a single check in place — used by the "Re-run"
       button on every row of the modal's pre-flight table.
  GET  /api/letsencrypt/orders/{order_id}/events
       Merged event timeline combining the typed
       `acme_order_events` rows with correlated
       `user_activity_logs` entries (resource_type =
       'letsencrypt_order' AND resource_id = order_id). The
       diagnostic modal auto-tails this timeline every 5 seconds
       while open.

Service-level checks (`backend/services/acme_diagnostics.py`):
  * DNS resolution via stdlib socket.gethostbyname_ex through
    run_in_executor (intentionally avoiding an aiodns runtime
    dep for v1.5.0).
  * Port-80 HEAD probe, target locked to the order's domains,
    success on HTTP 200 OR 404, warns on egress timeout
    (corp egress policies routinely blackhole outbound 80 —
    fail-hard would be too noisy).
  * SSRF guard: probe refuses non-public IPs and surfaces the
    skip in the diagnostic result; IPv4-mapped IPv6 normalisation
    closes the `::ffff:169.254.169.254` cloud-metadata vector.
  * HAProxy routing presence check: matches the order's
    cluster_ids to a port-80 HTTP frontend.
  * ACME account validity check against `letsencrypt_accounts`.
  * Agent presence check (>=1 active agent in target cluster).
  * Every sub-check wrapped in a wall-clock timeout to bound
    impact on the API event loop.

RBAC: ssl.read for run, ssl.read for events. Per-user 5/min rate
limit on both run and rerun, backed by the (user_id, action,
created_at DESC) composite index.

Frontend (`frontend/src/components/ACMEAutomation.js`):
  * "Diagnose" button on every order row + the existing
    "stuck order" warning row.
  * Modal with two tabs:
    - Pre-flight Checks (Antd Table with status pills + Re-run
      buttons + humanized error banner)
    - Event Log (Antd Timeline with auto-tail polling, scroll-
      to-bottom, pause-on-hover)
  * Correlation IDs surfaced in error banners and individual
    check fail details for backend-log lookup.

------------------------------------------------------------------
HEADLINE FEATURE B — Site Setup Wizard (Issue #14)
------------------------------------------------------------------
A single guided flow that creates a Backend + Servers + HTTP
Frontend (and optional HTTPS Frontend) in one atomic transaction.

Endpoints (`backend/routers/site_wizard.py`):
  POST /api/site-wizard/preview     — diff-preview the changeset
  POST /api/site-wizard/create      — atomic execute
  POST /api/site-wizard/reject      — clean rollback (including
                                       any wizard_staged ACME
                                       orders)
  GET  /api/site-wizard/drafts      — draft persistence
  PUT  /api/site-wizard/drafts/{id} — save/update
  DELETE /api/site-wizard/drafts/{id}

Feature surface:
  * One screen captures both backend (mode + servers) AND
    frontend (http + optional https + SSL mode) inputs.
  * SSL modes: ACME (new order, HTTP-01 only for v1.5.0),
    Upload (existing PEM), Existing (link to a stored cert),
    or None.
  * ACME-staged path: wizard_staged_until watermark on the
    `letsencrypt_orders` row defers finalisation until agent
    confirmation; per-mode reject cleanly cancels and rolls
    back the staged order.
  * Live diff preview against the cluster's current generated
    config (renderer-evolution noise stripped — track-sc<N>
    dedup, per-server cookie strip, defaults-cookie
    inheritance, listen-block flattening).
  * Draft persistence with PEM stripped at save time (private
    keys never round-trip through the drafts table).
  * Per-cluster multi-tenancy: drafts and wizard_staged orders
    are isolated to the creating user's cluster scope.

Frontend (`frontend/src/components/SiteWizard.js`):
  * 4-step Antd Steps flow: Backend → Frontend → SSL → Review.
  * Render the live diff preview inline before commit.
  * Antd Form-level validation mirrors backend Pydantic
    validators (numeric bounds, HAProxy reserved keywords, ALPN
    consistency, IPv6 scope-id, domain regex, server name
    dedup).

AUDIT CAMPAIGN — Rounds 1 → 22 (Bulgu #1 → #82)
------------------------------------------------------------------
v1.5.0 includes 22 adversarial review passes. Each round produced
its own commit set in the corporate development line; this squash
collapses those into the v1.5.0 release artefact. Highlights:

  Round 1-4   Site Wizard core: dry-run parity, single-line
              value injection guard, ACL -f pattern-file block,
              SSL parity, timeout regex, form-state pin.
  Round 5-7   defaults-cookie inheritance, server-named-cookie
              guard, fe/be mode mismatch, duplicate server
              names, health_check_uri + server_address
              validators.
  Round 8-10  cookie_name / cookie_options newline-injection
              guard, dry-run parity (round 9), TCP-mode HTTP-only
              feature blockers.
  Round 11    SSL name path traversal + health-check >= 1.
  Round 12-13 SSL & ACME deep dive (Bulgu #23-#32).
  Round 14    single-line value injection (Bulgu #33).
  Round 15-17 ACME multi-tenant UX, numeric bounds, HAProxy
              reserved keywords, ALPN/TLS consistency,
              all-backup, multi-domain & multi-user enterprise
              edges, drain/HSTS/post-completion (Bulgu
              #34-#53).
  Round 18-21 concurrency, agent state, TCP-mode HTTP-only,
              list size caps, IPv6 scope-id, preview account
              validation, TCP backend + balance uri reject
              (Bulgu #54-#61).
  Round 22    FE error visibility + 3x stale-data lockouts,
              referential integrity + cascade safety,
              authentication & authorization, multi-cluster
              isolation, apply_pending_changes concurrency,
              script injection + bulk import multi-tenancy,
              prefix-stripped signature comparison
              (Bulgu #62-#82).

NO CORPORATE-SPECIFIC ARTIFACTS
------------------------------------------------------------------
This squash deliberately sanitises corporate hostnames, container
registry references, and TLS secret names into generic
placeholders (`your-registry.example.com/your-org`,
`haproxy-openmanager*.example.com`, `wildcard-tls`,
`taylanbakircioglu/haproxy-openmanager-*`) so the public artefact
contains no internal infrastructure detail. Pilot / development
history that retained those values stays in the corporate fork
and is NOT part of this commit.

Taylan Bakırcıoğlu cb645b5ef9 CRITICAL FIX: Agent Offline Issue - Backend Tolerance for Legacy Agents 
🔴 PRODUCTION CRITICAL FIX - Agent HTTP 422 Validation Error

PROBLEM:
- Production agents sending heartbeat with flat system_info fields
- Backend Pydantic model was strict and rejecting unknown fields
- Agents going offline with 'Validation error in request data' (HTTP 422)

ROOT CAUSE:
- Legacy agents embed system_info as flat key-value pairs in heartbeat JSON
- Backend expected only defined fields, rejected extra fields
- No backward compatibility for agent format variations

SOLUTION - BACKEND ONLY (NO AGENT CHANGES):
✅ Added 'extra = "allow"' to AgentHeartbeat Pydantic Config
✅ Backend now accepts both formats:
   - Flat format: operating_system, kernel_version, etc. (legacy agents)
   - Nested format: system_info: {...} (future agents)
✅ Updated comments to clarify backward compatibility

IMPACT:
- ✅ ZERO CHANGES to production agent scripts
- ✅ Existing agents will work immediately after backend deploy
- ✅ Forward compatible with future agent upgrades
- ✅ Tolerant to agent format variations

SAFETY:
- Minimal change (3 lines)
- Pydantic still validates required fields
- Extra fields ignored silently (no breaking changes)
- Production agents continue without restart or upgrade

DEPLOYMENT:
1. Deploy backend (this commit)
2. Agents come online automatically (no action needed)
3. Agent upgrades can happen later (when convenient)

This fix ensures production stability without touching agent scripts.

Taylan Bakırcıoğlu 5c1d2e11f9 Fix agent offline issue and bulk import SSL parsing 
CRITICAL FIXES:
1. Agent Heartbeat Validation Error (HTTP 422)
   - Added missing 'system_info' field to AgentHeartbeat model
   - Agents were sending system_info but backend model didn't accept it
   - No agent script update needed - agents already send this field

2. Bulk Import SSL Parser Enhancement
   - Fixed parsing of multiple SSL certificates with alpn/npn parameters
   - Example: 'bind :443 ssl crt cert1.pem crt cert2.pem crt cert3.pem alpn h2,http/1.1'
   - Old parser stopped at first whitespace after crt path
   - New parser extracts all crt paths even with alpn/npn/ciphers after them
   - Added user-friendly warning for SSL parameters (alpn, npn, ciphers) that won't be imported

TECHNICAL DETAILS:
- backend/models/agent.py: Added system_info: Optional[Dict[str, Any]]
- backend/utils/haproxy_config_parser.py: Enhanced SSL bind parsing logic
  * Parse bind line by splitting and iterating through parts
  * Extract all crt paths before hitting SSL parameters
  * Detect and warn about alpn, npn, ciphers, ciphersuites parameters
  * Inform user these advanced options should be configured manually

USER IMPACT:
- Agents will come online after backend deployment (no reinstall needed)
- Bulk import will correctly parse configs with multiple SSL certs + alpn
- Clear warnings shown in UI about SSL parameters not imported
