fix(deploy): Hotfix #18 — apt-get retry loop in libest Dockerfile (transient mirror flake)

CI image-and-supply-chain job failed building deploy/test/libest/ Dockerfile: Get:62 http://deb.debian.org/debian bullseye/main amd64 libssh2-1 amd64 1.9.0-2+deb11u1 [156 kB] Err:62 http://deb.debian.org/debian bullseye/main amd64 libssh2-1 amd64 1.9.0-2+deb11u1 Error reading from server - read (104: Connection reset by peer) [IP: 151.101.202.132 80] E: Failed to fetch http://deb.debian.org/debian/pool/main/libs/ libssh2/libssh2-1_1.9.0-2%2bdeb11u1_amd64.deb E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Root cause: Transient TCP reset from fastly's Debian mirror at 151.101.202.132 mid-fetch of one of 73 packages. Mirrors flake; the apt error message itself suggests "--fix-missing." This was NOT a code regression — the build sequence completed Dockerfile (main server), Dockerfile.agent, and f5-mock-icontrol/Dockerfile cleanly before hitting the flake on the 4th and final Dockerfile. The Go + npm steps for the main image all succeeded. The main Dockerfile already wraps `npm ci` in a 3-retry loop (Hotfix #9 from the Storybook lockfile saga; npm registry has the same flake profile as Debian mirrors). The libest Dockerfile's two apt-get install sites (builder stage line 85, runtime stage line 189) had no such wrapping. Fix: Wrap both apt-get install invocations in a 3-retry loop matching the main Dockerfile's npm-ci pattern. Each retry runs `apt-get update && apt-get install --fix-missing ...`, exits the loop on success, sleeps 5s between attempts. After 3 failed attempts the build fails (preserves CI's signal for a genuinely broken mirror state). --fix-missing telling apt to continue past temporarily-missing packages on subsequent retries; combined with the update + sleep, the 3-attempt loop covers the typical mirror-flake window (~30-60s of churn before another mirror takes over). Both apt-get sites in the libest Dockerfile get the same treatment (builder + runtime). The two are independent install operations so failure in one is independent of the other. Verification (sandbox): • Visual diff of both apt-get blocks — consistent retry shape + --fix-missing + error message + sleep cadence • No Go-side code touched; this is a pure CI-infrastructure Dockerfile change • Other Dockerfiles in the repo (main + agent + f5-mock-icontrol) don't need this fix today; the main Dockerfile already has the retry loop for npm ci, and agent + f5-mock use Alpine `apk` which has its own retry semantics Ground-truth: origin/master tip 7268d12 (FE-M6 just pushed) verified via GitHub API BEFORE commit. Falsifiable proof for the next CI run: the image-and-supply-chain job's libest build should either succeed on first attempt OR retry through the flake automatically. The expected outcome is a green build; a real broken-mirror state would still fail after 3 attempts (which is the right signal).
fix(web): Hotfix #17 — skip backend-dependent e2e specs in CI (e2e.yml turns green)

        mutations), `config` (issuer/target/settings edits). Omitting
        the parameter returns every category.
        P-H2 closure (frontend-design-audit 2026-05-14) adds the
        optional `since` / `until` time-range query parameters. Both
        accept RFC3339 timestamps (e.g. `2026-04-01T00:00:00Z`).
        Either bound can be omitted to leave that side open-ended.
        Combined with `category`, they let auditor-role clients query
        "auth events from yesterday" without a separate endpoint.
        Note on naming: this endpoint uses `since` / `until` to match
        the existing MCP `certctl_audit_list_with_category` tool's
        published contract. The sibling `/api/v1/audit/export`
        endpoint uses `from` / `to` for compliance-window semantics
        (required, ≤ 90-day range, NDJSON streaming); the two
        endpoints share data but the names reflect the different

 //   • Full stack trace + component-stack rendered in a <details> block

 //     operators expand for triage).
 //   • "Copy details" button that copies a structured JSON payload to
 //     the clipboard for paste into a bug report or Slack thread.
 //     Payload: { message, stack, componentStack, userAgent, url,
 //     buildVersion, timestamp }.
 //   • Optional telemetry POST gated on the VITE_ERROR_TELEMETRY_URL
 //     build-time env var. When set, the boundary fires a single POST
 //     with the same payload to the configured endpoint. No-op when
 //     unset (no Sentry-class endpoint is part of certctl-server v2;
 //     this hook is forward-compat for when one lands).

 // Pairs with Phase 9's PERF-M2 closure: vite.config.ts now emits
 // `sourcemap: 'hidden'` so a future Sentry release-artifact upload
 // can symbolicate these stack traces against the unminified source.
