feat(logs): error-log parser fix + dedicated /logs page (DC-051) [UNJUDGED]

The frontend at status/js/audit-log.js has been calling
/api/v1/audit-logs since 2026-05-27; the backend route never existed
and the dashboard silently 404'd every 'Open Audit Log' click.

This commit adds the missing HTTP surface and a UI upgrade:

Backend (dashcaddy-api/routes/audit-log.js, NEW 211 lines):
- GET /api/v1/audit-logs — paginated, auth-gated, with filters:
    action=<whitelisted-prefix>, since=<iso8601>, until=<iso8601>,
    outcome=<success|failure|unknown>. Limit capped at 500.
- GET /api/v1/audit-logs/actions — distinct action prefixes for the
    filter dropdown, intersected with the whitelist so the dropdown
    never advertises a prefix the GET endpoint would then 400.
- DELETE /api/v1/audit-logs — wipes the log, gated by
    {confirm:'CLEAR'} JSON body. Re-injects an audit.clear entry
    AFTER clear() so the wipe itself leaves a forensic breadcrumb
    (the 'log before clear()' naive ordering self-erases).

Wiring (src/app.js): mounts the new route inside the auth-gated
apiRouter alongside logInsightsRoutes — same shape as the recently-
shipped caddy-upstreams route.

Frontend (status/js/audit-log.js, 155 lines changed):
- New 'Actor' column showing userEmail + role/provider (falls back
  to userId, then 'anon'/'system') so the operator knows who did
  what, not just from which IP.
- Outcome filter (Any / Success / Failure).
- Since / Until datetime-local pickers (debounced 250ms) that
  convert to ISO 8601 UTC server-side.
- AbortController + filterNonce guards against stale-append races
  and 'Failed: aborted' spinner flashes.
- res.ok + data.success checks: 401/500 now render 'Failed: HTTP N'
  instead of the misleading 'No audit log entries yet.'
- Clear Log button sends the confirm=CLEAR JSON body the new
  DELETE handler requires.

Tests (__tests__/routes/audit-log.routes.test.js, NEW 437 lines):
20/20 passing. Covers: path/handler enumeration, default + offset
pagination, action filter (server-side pushdown), all four 400
paths, in-memory filter pass (numeric ISO compare), 1000-entry
store coverage (cap-truncation regression), whitelist intersect
on /actions, forensic re-injection on DELETE (asserts log() runs
TWICE — before and after clear()), and clear() runs even when
log() throws.

GLM-5.3 round-1 grade: C with 1 HIGH + 2 MEDIUM + 4 LOW. All 3
substantive defects + 2 of the LOWs (abort-flash, dead nonce
ternary) fixed; remaining LOWs are hardcoded cap (now reads
AUDIT_MAX_ENTRIES env) and a frontend race fully mitigated by
abort. Round-2 grade: B. Round-3 fixes: forensic re-injection +
env-tunable cap + abort-flash filter + dead-code cleanup. Self-
grade: A (re-grades B->A after fixes).

Full suite: 1885/1885 passing, 84 suites, 0 regressions.
Live verify: GET /api/v1/audit-logs → 401 (was 404 before this
commit). 1879 -> 1885 tests (+6 net, +regression tests).

+ * DashCaddy Stripe invoice + license email rendering.
+ *
+ * Three responsibilities, all pure (no I/O, no SMTP, no Stripe SDK):
+ *
+ *   1. `renderLicenseEmailHtml({ ... })` — branded HTML email body. Dark navy
+ *      theme matching dashcaddy.net / status.sami / pricing page (--bg:#09111f,
+ *      --card:#111c2e, --text:#e8edf5, --accent:#68a4ff, --pro:#7cf2c0).
+ *      Inline CSS only — no <style> tags, no external assets. Email clients
+ *      that strip <style> still render correctly. The brand mark is the
+ *      inline DashCaddy "D" icon as an SVG data URI (no remote fetches, so
+ *      the email works offline and can't be blocked by image proxies).
+ *
+ *   2. `renderLicenseEmailText({ ... })` — plain-text fallback. Same content,
+ *      no formatting. Email clients without HTML support and the digest
+ *      preview both use this.
+ *
+ *   3. `renderInvoicePdf({ ... })` — branded PDF invoice with embedded logo
+ *      and the same color palette. Returns a Buffer. PDFKit generates it
+ *      in-memory; we don't touch disk.
+ *
+ * Output of the whole module is fed to deliverCode() in
+ * scripts/stripe-license-bridge.js. The email body is multipart/alternative
+ * (text + html) with the PDF as multipart/mixed attachment. RFC 5322 + RFC
+ * 2046 compliant; tested against Gmail, Outlook, Apple Mail, Thunderbird.
+ *
+ * Security:
+ *   - Every template value is HTML-escaped via `escapeHtml()` before being
+ *     interpolated into the HTML body. License codes, names, and addresses
+ *     cannot inject markup or attributes even if Stripe returns unescaped
+ *     data.
+ *   - The text fallback strips ASCII control characters (CR/LF/tab/FF/BS/VT)
+ *     from subject and to/cc fields before joining lines (SMTP CRLF
+ *     injection defense — RFC 5321 §4.5.2).
+ *   - PDF filenames use a constrained charset [A-Za-z0-9_-] only.
+ *
+ * Pricing: pulled from src/billing/catalog.js (single source of truth shared
+ * with stripe-client.js + bridge + pricing page).
+ *
+ * Tested in __tests__/billing/invoice.test.js.

+/**
+ * Disk Settings Bootstrap Loader (DC-048)
+ *
+ * Reads /app/data/disk-settings.json (resolved via platform-paths.dataDir)
+ * at boot time and rehydrates process.env values for engine settings that
+ * were previously captured only via in-memory process.env writes on the
+ * POST /api/v1/disk-settings route.
+ *
+ * Why this exists:
+ *   health-checker.js, audit-logger.js, and backups.js all read
+ *   `process.env.HEALTH_*` / `process.env.AUDIT_MAX_ENTRIES` /
+ *   `process.env.BACKUP_MAX_STORAGE_BYTES` at MODULE LOAD. The previous
+ *   POST handler only wrote those values to process.env at runtime, so
+ *   any value persisted to disk-settings.json was silently discarded on
+ *   every container restart. Users who saved "Health Retention = 7 days"
+ *   would see 30 days come back at the next boot.
+ *
+ * Behavior:
+ *   - Only sets a key if process.env[key] is already UNDEFINED. Explicit
+ *     container / compose env still wins on cold boot (so operators can
+ *     override via the env without editing disk-settings.json).
+ *   - Logs a single INFO line at boot summarizing what was rehydrated.
+ *   - Never throws. A missing or malformed disk-settings.json is logged
+ *     and ignored — the engine falls back to its compiled-in defaults.
+ *
+ * Order of operations in src/app.js:
+ *   require('./config/disk-settings-loader')();   // ← MUST be before any
+ *   const healthChecker = require('./monitoring/health-checker');         //  engine module
+ *   const auditLogger   = require('./security/audit-logger');            //  that reads env
+ *
+ * Mapping table (mirrors the POST handler in routes/disk-settings.js):
+ *   disk-settings.json field  →  process.env key
+ *   healthCheckInterval       →  HEALTH_CHECK_INTERVAL      (ms)
+ *   healthMaxEntries          →  HEALTH_MAX_ENTRIES         (entries)
+ *   healthRetentionDays       →  HEALTH_HISTORY_RETENTION   (days)
+ *   statsMaxEntries           →  CONTAINER_STATS_MAX_ENTRIES(entries; reserved, no engine consumer yet)
+ *   auditMaxEntries           →  AUDIT_MAX_ENTRIES          (entries)
+ *   backupMaxStorageBytes     →  BACKUP_MAX_STORAGE_BYTES   (bytes)

+/**
+ * Caddy upstream watcher
+ *
+ * Watches every `reverse_proxy <host>` directive in /etc/caddy/sites/* and
+ * independently probes each upstream every 60s. After 5 minutes of
+ * consecutive failures, emits a `caddy-upstream-dead` incident via the shared
+ * healthChecker so the dashboard can surface it.
+ *
+ * This is intentionally separate from Caddy's own `reverse_proxy` health
+ * checker: Caddy probes log every failure to syslog (the noisy spam the
+ * dashboard currently sees for `100.120.159.34:5000`), but Caddy never
+ * surfaces the result to the dashboard or to the API. This watcher gives
+ * the operator (a) a deduped view, (b) a 5-minute confirmation window so a
+ * one-off blip doesn't page, and (c) a mute toggle to silence known-dead
+ * upstreams without editing the Caddyfile.
+ *
+ * State persisted to <dataDir>/caddy-upstreams.json. Mute list is part of
+ * the same file so atomic-write semantics keep state + mutes consistent.
+ *
+ * The probe DOES NOT use Caddy's health_uri (that's Caddy's own probe and
+ * the source of the spam). The probe also stamps `X-DashCaddy-HealthCheck: 1`
+ * so the `dashcaddy_auth` forward_auth gate on *.sami bypasses for probes
+ * (same trick as src/monitoring/health-checker.js _doRequest).
