feat: dashboard theme overhaul — light content area with branded teal sidebar

Complete frontend visual redesign using certctl logo color palette:
- Deep teal sidebar (#0c2e25) with prominent centered logo (64px in white pill)
- Light content area (#f0f4f8) with white cards and visible borders
- Brand colors from logo: teal (#2ea88f), blue (#3b7dd8), orange (#e8873a), green (#4ebe6e)
- Inter + JetBrains Mono typography, colored stat card top borders
- All 17 pages + 7 components updated (25 files, ~700 lines changed)
- 15 new dashboard screenshots replacing old dark theme screenshots
- Prometheus metrics e2e test added, integration test mock fixes
- Docs updated: architecture.md theme description, testing-guide.md DNS-PERSIST-01 coverage

+### Why manual QA on top of automated tests?
 
 Automated tests mock dependencies and run in isolation. Manual QA validates the full integrated stack: real PostgreSQL, real HTTP, real agent binary, real file I/O, real scheduler timing. It catches issues that unit tests can't: migration ordering, Docker networking, env var parsing, browser rendering, and timing-dependent scheduler behavior.

+### 6.2 ACME DNS Challenge Configuration
+
+**Test 6.2.1 — List ACME issuer with DNS-01 configuration**
+
+```bash
+curl -s -H "$AUTH" "$SERVER/api/v1/issuers/iss-acme-le" | jq '{id, type, config}'
+```
+
+**What:** Retrieves the ACME Let's Encrypt issuer and verifies its configuration.
+**Why:** ACME issuers configured for DNS-01 challenges need their solver scripts accessible for wildcard certificate support.
+**Expected:** HTTP 200. `type` = "acme". `config` may include challenge type and DNS script paths.
+**PASS if** HTTP 200 and type matches. **FAIL** otherwise.
+
+---
+
+**Test 6.2.2 — Create ACME issuer with DNS-PERSIST-01**
+
+Edit `deploy/docker-compose.yml` to set environment variables for ACME DNS-PERSIST-01:
+- `CERTCTL_ACME_CHALLENGE_TYPE: dns-persist-01`
+- `CERTCTL_ACME_DNS_PERSIST_ISSUER_DOMAIN: le.example.com`
+- `CERTCTL_ACME_DNS_PRESENT_SCRIPT: /usr/local/bin/dns-present.sh`
+- `CERTCTL_ACME_DNS_CLEANUP_SCRIPT: /usr/local/bin/dns-cleanup.sh`
+
+Restart and verify the issuer accepts the config:
+
+```bash
+curl -s -H "$AUTH" "$SERVER/api/v1/issuers/iss-acme-le" | jq '{id, type}'
+```
+
+**What:** Verifies that ACME issuers read DNS-PERSIST-01 configuration from environment variables.
+**Why:** DNS-PERSIST-01 requires a standing TXT record per IETF draft. The issuer must know the issuer domain and support this challenge type.
+**Expected:** HTTP 200. ACME issuer still functional.
+**PASS if** HTTP 200 and issuer still works. **FAIL** if 500 or issuer broken.
