Oliver Kieselbach f1e89146cb feat(backend): M5.c.1 GET /api/sessions/{id}/signals — Inspector SignalLog read
First of three V2 Inspector read endpoints (Plan §M5). Returns the SignalLog
for a session — ordered by SessionSignalOrdinal, bounded by a caller-supplied
maxResults with a hard 5000 cap.

- ISignalRepository.QueryBySessionAsync added alongside the existing
  StoreBatchAsync. Uses Azure Tables filter on PartitionKey = {tenant}_{session};
  the D19(ordinal) RowKey padding means lex order already matches numeric
  order, so the explicit sort on return is a redundancy guard — cheap
  invariant check, not a real cost.
- TableSignalRepository.FromEntity — reverse mapping (entity → SignalRecord)
  that mirrors ToEntity, including TableStorageChunking.ReassembleProperty
  for oversized PayloadJson. Round-trip tested end-to-end.
- GetSessionSignalsFunction.Run — follows the same shape as
  GetSessionEventsFunction: RequestContext.TargetTenantId resolved by
  PolicyEnforcementMiddleware, Global-Admin cross-tenant fallback via
  SessionsIndex when the effective-tenant query comes up empty.
- ParseMaxResults extracted as a pure helper taking the raw query string
  (not HttpRequestData) so it's unit-testable without mocking the abstract
  Worker HttpRequestData class.
- Endpoint registered in EndpointAccessPolicyCatalog under MemberRead +
  TenantScoping.QueryParam (same policy as sessions/{id}/events). Without
  this the fail-closed catalog would reject the route with 403 — verified
  by the EndpointPolicyCatalogCompletenessTests.

9 new tests (614/614 backend green): ParseMaxResults defaults / garbage /
in-range / cap / negative / null query string (6), plus FromEntity
round-trip (simple payload + oversized-chunked payload).
