shankar0123 4e5522a999 F-001/F-002/F-003: CRL prefix-scan, digest error sanitization, ctx-aware sleeps
F-001 (P3): GenerateDERCRL scoped to issuer via composite index
  - Add RevocationRepository.ListByIssuer leveraging migration 000012's
    idx_certificate_revocations_issuer_serial composite index as a
    prefix-scan target. Previously CAOperationsSvc.GenerateDERCRL called
    ListAll() and filtered by IssuerID in Go — O(total revocations)
    regardless of how many revocations belonged to the target issuer.
  - Rewrite GenerateDERCRL to call ListByIssuer(ctx, issuerID) so PostgreSQL
    drives a prefix scan of the composite index. Drops the in-memory filter.
  - New regression test in ca_operations_test.go asserts the CRL hot path
    invokes ListByIssuer exactly once and never ListAll, and that the
    issuerID is threaded through correctly.

F-002 (P3): digest.go admin-auth endpoints no longer leak internal errors
  - PreviewDigest (GET /api/v1/digest/preview) and SendDigest
    (POST /api/v1/digest/send) previously wrote err.Error() into the HTTP
    response body on 500s. Replace with slog.Error server-side logging plus
    a generic "internal error" response body, matching the house pattern
    in certificates.go and export.go.

F-003 (P4): three blocking time.Sleep sites now honor ctx cancellation
  - internal/connector/issuer/acme/acme.go:672 (DNS-01 propagation wait)
    now runs under a select{case <-ctx.Done(): CleanUp + return ctx.Err();
    case <-time.After(d):} so graceful shutdown doesn't get stuck behind
    the propagation delay.
  - internal/connector/issuer/acme/acme.go:786 (dns-persist-01 propagation
    wait) same pattern, returns ctx.Err() on cancel.
  - cmd/agent/main.go:272 (polling backoff inside the heartbeat loop) now
    wraps the sleep in select{case <-ctx.Done(): continue; case <-time.After(backoff):}
    so the outer <-ctx.Done() case on the parent loop fires cleanly.

Verification: build, vet, and race-enabled short tests green across all
55+ packages. govulncheck reports zero vulnerabilities in the code path.
No migration needed — F-001 reuses the existing 000012 composite index.
No frontend changes.
