[AZ-503] [AZ-504] Cycle 5 Steps 11-15 sync

Wrap up cycle 5 verification + documentation:
- Steps 10/11 wrap-up reports (implementation_completeness +
  implementation_report) for the AZ-503-foundation + AZ-504 batch.
- Step 12 test-spec sync: AZ-503-foundation/AZ-504 ACs appended;
  AZ-505 deferred ACs recorded.
- Step 13 update-docs: architecture, data-model, glossary, module-
  layout, uav-tile-upload contract (v1.1.0), DataAccess + Services
  + Tests module docs synced; new common_uuidv5.md module doc.
- Step 14 security audit: PASS_WITH_WARNINGS; 0 new Critical/High;
  2 new Low informational (F1 flightId provenance, F2 pgcrypto
  deploy gap).
- Step 15 performance test: PASS_WITH_INFRA_WARNINGS; PT-08
  passed twice (AZ-504 fix verified); PT-01/02 failed due to
  recurring local Docker/colima DNS cold-start (not an app
  regression). Cycle-3 perf-harness leftover stays OPEN with
  replay #5 documented.
- Autodev state moved to Step 16 (Deploy).

AZ-503 (cycle 5) added: `Az503ColumnsExistAndLocationHashIsNotNull` (asserts the 4 new columns + `location_hash NOT NULL`), `Az503NewUniqueIndexCoversIntegerKeyAndFlightId` (asserts `idx_tiles_unique_identity` columns + `COALESCE(flight_id, ...)` predicate), `Az503LocationHashBackfillIsDeterministic` (computes `pg_temp.uuidv5("18/12345/23456")` and compares byte-for-byte against the C# `Uuidv5.Create` output on 3 sampled live rows); the AZ-484 supersession test was renamed to `Az503MigrationSupersedesAz484UniqueIndex` and asserts `idx_tiles_unique_location_source` no longer exists.
 - `JwtIntegrationTests` (added by AZ-487 cycle 2; helpers consolidated by AZ-491 cycle 3; iss/aud scenarios added by AZ-494 cycle 3) — `AnonymousRequest_To_AnyEndpoint_Returns401`, `ExpiredToken_Returns401`, `InvalidSignature_Returns401`, `ValidToken_Returns200_OnHealthyEndpoint`, `WrongIssuer_Returns401` (AZ-494 AC-1), `WrongAudience_Returns401` (AZ-494 AC-2), `SwaggerDocument_AdvertisesBearerSecurityScheme`. HS256 token minting lives in the shared `SatelliteProvider.TestSupport.JwtTokenFactory` (consumed via `ProjectReference`); runner-specific concerns (`JwtTestHelpers.ResolveSecretOrThrow` / `ResolveIssuerOrThrow` / `ResolveAudienceOrThrow`, `MintAuthenticated` / `MintExpired` convenience wrappers that auto-fill iss+aud from env, `AttachDefaultAuthorization`, `DefaultSubject = "integration-tests"`) remain in this project. The test runner sets `JWT_SECRET` + `JWT_ISSUER` + `JWT_AUDIENCE` on the API container and attaches a Bearer token (with matching iss/aud) to every existing test's HTTP requests so the pre-cycle-2 suite continues to pass.
-- `UavUploadTests` (added by AZ-488, cycle 2; coordinate-counter promoted to defense-in-depth by AZ-493 cycle 3) — `HappyPathSingleItem_PersistsRow`, `MixedBatch_ReturnsPerItemResults`, `MultiSourceCoexistence_AZ484_Cycle2`, `SameSourceUpsert_AZ484_Cycle2`, `NoToken_Returns401`, `ValidTokenWithoutGpsPermission_Returns403`, `OversizedBatch_Returns400`. The wall-clock-seeded `_coordinateCounter` is retained as a belt-and-suspenders safeguard alongside the AZ-493 startup DB-reset (below) — if a developer runs with `--keep-state`, or the DB-reset path is skipped for any reason, the wall-clock seed still spreads coordinates across runs so the per-source unique index does not collide.
+- `UavUploadTests` (added by AZ-488, cycle 2; coordinate-counter promoted to defense-in-depth by AZ-493 cycle 3; AZ-503 cycle 5 added 2 more tests) — `HappyPathSingleItem_PersistsRow`, `MixedBatch_ReturnsPerItemResults`, `MultiSourceCoexistence_AZ484_Cycle2`, `SameSourceUpsert_AZ484_Cycle2`, `NoToken_Returns401`, `ValidTokenWithoutGpsPermission_Returns403`, `OversizedBatch_Returns400`, plus AZ-503: `MultiFlightUavRowsCoexist_AZ503_AC3` (two flights at the same cell → two rows, one `location_hash`, two `file_path`s under `./tiles/uav/{flight_id}/...`) and `FloatRoundingDoesNotBreakIdempotence_AZ503_AC4` (two uploads with float-distinct `latitude` recomputed from `TileToWorldPos` collapse to a single row because the conflict key is integer-only). The AZ-503 migration made `location_hash NOT NULL`, so the cycle-2 `MultiSourceCoexistence_AZ484_Cycle2` seeder was updated to compute `location_hash` via `Uuidv5.Create` (canonical name `"{zoom}/0/0"`) before the raw SQL `INSERT` — this required adding a `ProjectReference` from `SatelliteProvider.IntegrationTests` to `SatelliteProvider.Common`. The wall-clock-seeded `_coordinateCounter` is retained as a belt-and-suspenders safeguard alongside the AZ-493 startup DB-reset (below) — if a developer runs with `--keep-state`, or the DB-reset path is skipped for any reason, the wall-clock seed still spreads coordinates across runs so the unique index does not collide.
 - `StubAndErrorContractTests` (existing) — updated in cycle 2 to drop the legacy `StubUpload_Returns501` expectation since AZ-488 implemented the endpoint.

 - Communicates with the API exclusively via HTTP for end-to-end tests; communicates with PostgreSQL directly only via the dedicated DB-reset hook + the existing `MigrationTests` schema assertions.
