[AZ-487] [AZ-488] docs: cycle 2 doc sync (task mode)

Step 13 (Update Docs) for cycle 2. Most cross-cutting docs were
already updated during Step 10 (architecture.md, glossary.md,
components/03_tile_downloader, modules/api_program.md, data_model.md,
contracts/api/uav-tile-upload.md). This commit completes the remaining
module-level + module-layout updates and writes the cycle-2 ripple log.

* modules/common_configs.md: + UavQualityConfig section and
  appsettings-section row (UavQuality).
* modules/common_dtos.md: + UavTileMetadata, UavTileBatchMetadataPayload,
  UavTileBatchUploadResponse, UavTileUploadResultItem, UavTileUploadStatus,
  UavTileRejectReasons (closed enumeration v1.0.0).
* module-layout.md: refresh Common (+ UavQualityConfig + UAV DTOs),
  TileDownloader (+ UavTileQualityGate, UavTileUploadHandler, +
  SixLabors.ImageSharp 3.1.11 PackageReference), and WebApi (+
  Authentication/*, DTOs/UavTileBatchUploadRequest, + JwtBearer 8.0.21
  PackageReference). Updates the "Last Updated" stamp to cycle 2.
* modules/tests_unit.md: replace the obsolete "only a dummy test"
  description; add cycle-2 AZ-487 / AZ-488 test classes
  (AuthenticationServiceCollectionExtensionsTests, JwtTokenFactoryTests,
  UavTileQualityGateTests, UavTileUploadHandlerTests, UavTileFilePathTests,
  PermissionsRequirementTests) + new ProjectReference / package
  references.
* modules/tests_integration.md: + JwtIntegrationTests, UavUploadTests
  (incl. wall-clock-seeded coordinate counter rationale from the Step 11
  fix), and the StubAndErrorContractTests update for the removed 501
  stub.
* ripple_log_cycle2.md (new): cycle-2 reverse-dependency scan results
  showing every importer of the new symbols resolves inside the three
  already-updated components (WebApi, TileDownloader, Common). No
  unexpected ripple, no heuristic fallback needed.

 ## Internal Logic
 `StorageConfig.GetTileSubdirectoryPath` buckets tiles by dividing X/Y coordinates by 1000, preventing filesystem performance degradation from too many files in one directory.
