mix 56a4fa892d Phase 8: level-2 differentiated rate limits (spec 7.4)
The journal-milter, until now a pure monitor, now refuses a message with a
4xx tempfail (RespTempFail/451) at MAIL FROM when a per-domain or per-
application limit is exceeded. Key is the client IP; the count is
COUNT(DISTINCT queue_id) over a sliding window reusing the send log; the
limit applies only when a non-empty IP binding matches the client (empty
binding => level-1 only, per spec 7.4). Enforcement is fail-open on the
milter's own errors — a limiter malfunction never blocks mail, and Postfix's
level-1 anvil limit stays the independent backstop. Refused messages are
recorded in send_log with status "rejected" for UI visibility.

- store/ratelimits.go: RateLimit type (+Active/AllowsIP), id-keyed get/set/
  delete for the panel, name/login-keyed lookup + windowed distinct-message
  count for the milter, DeleteRateLimitsForDomain. No migration — the
  rate_limits table has existed since Phase 2.
- milter: enforce at MailFrom, fail-open helper overLimit, InsertRejected.
- web: server-side validated IP/ceiling/window forms on the domain page and
  per application; routes POST /domains/{id}/ratelimit and
  /applications/{aid}/ratelimit. Milter reads rows live, so no reload.
- domain/app services clear limits on deletion (rate_limits has no FK cascade).

Unit tests + container e2e (p8) green: refusal on both scopes, unregistered
IP ignored, fail-open with the panel stopped.
