[AZ-315] Sync architecture docs after coupling refactor

Phase C of architecture coupling refactor (epic AZ-309). Closes the
last baseline finding (F5 — DataAccess incorrectly documented as
importing Common) and synchronizes the rest of _docs/02_document/
with the post-split project layout from AZ-312/313/314:

- module-layout.md: per-component sections for the three new csprojs
  with explicit ProjectReferences and the no-cross-sibling-reference
  invariant the split enforces.
- architecture.md: components and internal-communication tables
  updated to show calls flow through Common interfaces.
- architecture_compliance_baseline.md: F1..F5 marked Resolved with
  task IDs and commit refs; baseline summary now 0 findings.
- diagrams/components.md, components/03_tile_downloader/description.md,
  modules/{common_interfaces,services_tile_service,
  services_google_maps_downloader,tests_unit}.md updated for the
  split, RateLimitException relocation, and new ITileService methods.

Documentation-only batch — no code, no tests, no build changes.
Epic AZ-309 complete (6 tasks across 3 batches).

# Module: Common/Interfaces
## Purpose
Service contracts defining the application's core operations. Implementations live in `SatelliteProvider.Services`.
Service contracts defining the application's core operations. Implementations live in the per-component service projects (`SatelliteProvider.Services.TileDownloader`, `SatelliteProvider.Services.RegionProcessing`, `SatelliteProvider.Services.RouteManagement`). Cross-component runtime calls between Layer-3 components flow exclusively through these interfaces — there are no compile-time `ProjectReference` entries between the three sibling service projects.

- `DownloadAndStoreTilesAsync(double lat, double lon, double sizeMeters, int zoomLevel, CancellationToken) → Task<List<TileMetadata>>`: downloads missing tiles for a region and returns all tile metadata (existing + new)
- `GetTileAsync(Guid id) → Task<TileMetadata?>`: retrieve a single tile by ID
- `GetTilesByRegionAsync(double lat, double lon, double sizeMeters, int zoomLevel) → Task<IEnumerable<TileMetadata>>`: query tiles within a geographic region
- `GetOrDownloadTileAsync(int z, int x, int y, CancellationToken) → Task<TileBytes>`: serve a tile by Z/X/Y, hitting cache, then repository, then downloader (added in AZ-310)
- `DownloadAndStoreSingleTileAsync(double latitude, double longitude, int zoomLevel, CancellationToken) → Task<TileMetadata>`: download one tile by lat/lon and persist (added in AZ-311)
### IRegionService
- `RequestRegionAsync(Guid id, double lat, double lon, double sizeMeters, int zoomLevel, bool stitchTiles) → Task<RegionStatus>`: creates a region record and enqueues for async processing
