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).
