[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.

 # Module: Tests/SatelliteProvider.Tests
 
 ## Purpose
-Unit test project. Currently contains only a single dummy test as a placeholder.
+Unit test project for component-internal logic. Original AZ-2/AZ-3 era had only a placeholder dummy; the suite has since grown across the AZ-285..AZ-380 baseline + cycle 1 (AZ-484) + cycle 2 (AZ-487, AZ-488) tracks. The "dummy test only" note in older revisions of this file is obsolete — the project now hosts the full unit suite executed by `scripts/run-tests.sh --unit-only` and CI's `01-test.yml`.
 
-## Public Interface
+## Public Interface (test classes)
 
-### DummyTests
-- `Dummy_ShouldWork()`: asserts `1 == 1`
+Existing baseline (pre-cycle-2) test classes cover `TileService`, `RegionService`, `RouteService`, geo math, repositories, validators, idempotency, and migration helpers — not enumerated exhaustively here. Cycle-2 additions:
+
+### AZ-487 — JWT validation baseline
+- `Authentication/AuthenticationServiceCollectionExtensionsTests` — `AddSatelliteJwt_RegistersJwtBearerScheme`, `AddSatelliteJwt_ThrowsOnMissingSecret`, `AddSatelliteJwt_ThrowsOnShortSecret`.
+- `Authentication/JwtTokenFactoryTests` — `Create_ProducesTokenValidatedByMatchingParameters`, `CreateExpired_TokenFailsValidationWithLifetimeException`, `Create_WithExtraClaims_PropagatesClaimsThroughValidation`.
+- `TestUtilities/JwtTokenFactory` — helper that mints HS256 tokens with the same `TokenValidationParameters` used in production. Adjusts `notBefore` for negative-lifetime requests so `JwtSecurityToken` accepts the value and downstream lifetime validation can fire (`IDX12401` workaround documented inline).
+
+### AZ-488 — UAV tile upload
+- `UavTileQualityGateTests` — one happy path + ≥ 1 reject path per rule (Rule 1 INVALID_FORMAT × 2, Rule 2 SIZE_OUT_OF_BAND × 2, Rule 3 WRONG_DIMENSIONS × 1, Rule 4 CAPTURED_AT_FUTURE / _TOO_OLD × 2, Rule 5 IMAGE_TOO_UNIFORM × 1) + rule-ordering determinism. Uses a `FixedTimeProvider` for Rule-4 isolation and `UavTileImageFactory` for deterministic JPEG fixtures.
+- `UavTileUploadHandlerTests` — end-to-end with a mocked `ITileRepository`: 1-item happy path, 3-item mixed batch (file written + `InsertAsync` called only for accepted), per-source UPSERT pass-through.
+- `UavTileFilePathTests` — verifies `BuildUavTileFilePath` produces `tiles/uav/{z}/{x}/{y}.jpg` for sample (z, x, y) tuples and that integer-typed coordinates make string-injection of path traversal impossible.
+- `Authentication/PermissionsRequirementTests` — `PermissionsAuthorizationHandler` correctly accepts a `permissions` claim shaped as a single string OR as a JSON array, rejects when the requested permission is absent, and short-circuits when the principal has no `permissions` claim at all.
+- `TestUtilities/UavTileImageFactory` — programmatic JPEG factories used by the gate + handler tests: `CreateValidJpeg(width, height, seed)`, `CreateUniformJpeg`, `CreatePng` (for Rule 1 negative path).
 
 ## Internal Logic
-No meaningful test logic.
+- Tests follow Arrange / Act / Assert. Time-dependent paths inject a `FixedTimeProvider` (cycle-2 addition) so Rule 4 has deterministic age windows.
+- `JwtSecurityTokenHandler.MapInboundClaims = false` is set explicitly in JWT tests so claims read by their original names (`sub`, `permissions`, …) rather than the framework-remapped names.
 
 ## Dependencies
-- Project references: `SatelliteProvider.Services.TileDownloader`, `SatelliteProvider.Services.RegionProcessing`, `SatelliteProvider.Services.RouteManagement`, `SatelliteProvider.Common`, `SatelliteProvider.DataAccess`
-- NuGet: xUnit (2.5.3), Moq (4.20.72), FluentAssertions (8.8.0), coverlet.collector (6.0.0), Microsoft.NET.Test.Sdk (17.8.0), Microsoft.Extensions.* (Caching.Memory, Configuration, DI, Logging, Options, Http)
-- Has `appsettings.json` copied to output (empty config for potential future test setups)
+- Project references: `SatelliteProvider.Services.TileDownloader`, `SatelliteProvider.Services.RegionProcessing`, `SatelliteProvider.Services.RouteManagement`, `SatelliteProvider.Common`, `SatelliteProvider.DataAccess`, `SatelliteProvider.Api` (for the Authentication tests — added in AZ-487).
+- NuGet: xUnit (2.5.3), Moq (4.20.72), FluentAssertions (8.8.0), coverlet.collector (6.0.0), Microsoft.NET.Test.Sdk (17.8.0), Microsoft.Extensions.* (Caching.Memory, Configuration, DI, Logging, Options, Http), `Microsoft.AspNetCore.Authentication.JwtBearer` 8.0.21 (added by AZ-487 for the DI + handler tests), `SixLabors.ImageSharp` 3.1.11 (added by AZ-488 for the gate tests).
+- `appsettings.json` copied to output (used by Authentication tests for the `Jwt` section binding scenario).
 
 ## Consumers
-- CI pipeline (`01-test.yml`) runs `dotnet test` against this project
+- CI pipeline (`01-test.yml`) and `scripts/run-tests.sh --unit-only` run `dotnet test` against this project.
 
 ## Tests
-This IS the test module. Coverage: effectively zero (only a dummy test).
+This IS the test module. Cycle-2 added ~25 unit tests on top of the existing baseline; the full project executes in seconds (no external services required).
