[AZ-312] [AZ-313] [AZ-314] Split Services into per-component csprojs

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.
