Phase B of architecture coupling refactor (epic AZ-309). Replaces
the monolithic SatelliteProvider.Services with three per-component
csprojs to add a compiler-enforced module boundary (resolves F4):
- SatelliteProvider.Services.TileDownloader
- SatelliteProvider.Services.RegionProcessing
- SatelliteProvider.Services.RouteManagement
DI registrations relocated into per-component AddTileDownloader /
AddRegionProcessing / AddRouteManagement extension methods called
from Program.cs. RateLimitException moved to Common/Exceptions/ to
keep the three new csprojs as siblings (no Region->TileDownloader
ProjectReference). Dockerfiles and consumer csprojs (Api, Tests)
rewired to the new project paths. No DI lifetime or hosted-service
order changes.
Build: 0 warn, 0 err. Unit tests: 40/40. Smoke integration: green.

Move cache+DB+download logic for /tiles/{z}/{x}/{y} and
/api/satellite/tiles/latlon out of Program.cs into TileService.
Endpoints now inject only ITileService + ILogger. Service owns
IMemoryCache (1h absolute / 30min sliding preserved). Added
TileBytes DTO; ITileService gains GetOrDownloadTileAsync and
DownloadAndStoreSingleTileAsync. 5 new unit tests cover cache
hit, repo hit, downloader fallback, and AZ-311 happy + error.
Build clean (0/0), unit suite 40/40. Resolves architecture
baseline F3 in code (docs handled by AZ-315).

- Baseline metrics, list of changes, and analysis (research findings,
refactoring roadmap) for the coupling refactor run
- Six task specs AZ-310..AZ-315 covering endpoint routing through
ITileService, Services csproj split, consumer rewire, DI extension
methods, and docs sync
- Existing test coverage assessment for Phase 3 safety net gate
- Dependencies table updated with the refactor block

- Add SatelliteProvider.DataAccess project reference to test csproj
(enables mocking ITileRepository / IRegionRepository / IRouteRepository)
- Replace DummyTest placeholder with InfrastructureTests covering:
* All mockable interfaces (ISatelliteDownloader, repos, queue, services)
can be mocked via Moq
* TileService can be constructed with mocked dependencies
* Test coordinate fixtures load with expected values
- Add Fixtures/TestCoordinates.cs with REG-01..REG-03 + ROUTE-01/04/06
shared test data
- Archive AZ-285 to _docs/02_tasks/done/
- Batch 1 review report: PASS_WITH_WARNINGS (Low/Spec-Gap deferred AC-2,
Low/Maintainability pre-existing FluentAssertions 8.x license note)
Verification: docker dotnet test run — 4/4 tests pass in 2.35s.
