Oleksandr Bezdieniezhnykh b0fffa6d42 [AZ-284] Autodev baseline + testability refactor

Phase A baseline outputs from /autodev (Steps 1-5):
- Problem & solution docs (_docs/00_problem, _docs/01_solution)
- Codebase documentation (_docs/02_document) incl. architecture,
  module-layout, glossary, system-flows, baseline compliance scan
- Test specs (blackbox, performance, resilience, security, resource,
  traceability matrix)
- Test task decomposition (_docs/02_tasks/todo): AZ-285..AZ-290
- Testability refactor (_docs/04_refactoring/01-testability-refactoring):
  - TC-01 Move DownloadedTileInfoV2 + new ExistingTileInfo to Common.DTO
  - TC-02 Replace dead ISatelliteDownloader API with real signatures
  - TC-03 GoogleMapsDownloaderV2 implements ISatelliteDownloader
  - TC-04 TileService depends on ISatelliteDownloader (mockable)
  - TC-05 DI + endpoints use ISatelliteDownloader
- Test runner scripts (scripts/run-tests.sh, run-performance-tests.sh)
- Autodev state pointer (_docs/_autodev_state.md)

Prepares the codebase for AZ-285..AZ-290 unit/integration test work.

Resilience Test Scenarios

RS-01: API Startup with Database Ready

Trigger: Start API container after PostgreSQL is healthy Observable: API responds to HTTP requests Pass criterion: API returns non-5xx response within 60s of container start

RS-02: Database Migrations on Fresh Start

Trigger: Start API against empty database Observable: All 11 migrations execute successfully Pass criterion: API starts without error; all tables exist; schemaversions table has 11 entries

RS-03: Region Processing Survives Tile Download Failure

Trigger: Submit region request where some tiles may fail (rate limit / timeout) Observable: Region either completes (with partial tiles) or is marked "failed" Pass criterion: Status is either "completed" or "failed" (never stuck in "processing" indefinitely); max processing time < 300s

RS-04: Queue Capacity Limit

Trigger: Submit 1001+ region requests rapidly (exceeds capacity 1000) Observable: Queue rejects overflow requests Pass criterion: First 1000 accepted; subsequent requests return error or are dropped; no crash

RS-05: Concurrent Download Limit Respected

Trigger: Submit large region (many tiles) and observe download concurrency Observable: At most MaxConcurrentDownloads (4) HTTP requests to Google Maps simultaneously Pass criterion: No more than 4 concurrent outbound tile requests at any point (behavioral; requires observation or logging)

RS-06: Route Processing with All Regions Completing

Trigger: Create route with requestMaps=true, wait for completion Observable: Route transitions from processing to ready Pass criterion: mapsReady=true; no regions stuck in "processing"
