[AZ-371] Refactor C18: magic numbers to ProcessingConfig/MapConfig

Browse Source 
Promotes 8 operational levers into config keys with defaults that match
the prior source literals byte-for-byte:
  ProcessingConfig: RegionProcessingTimeoutSeconds (300),
  RouteProcessingPollIntervalSeconds (5),
  MaxRoutePointSpacingMeters (200), LatLonTolerance (0.0001).
  MapConfig: TileSizePixels (256), AllowedZoomLevels ([15..19]),
  RetryBaseDelaySeconds (1), RetryMaxDelaySeconds (30).

Sites updated: RegionService, RouteProcessingService,
RoutePointGraphBuilder, RouteValidator, RouteService 4-arg ctor,
RouteImageRenderer, GoogleMapsDownloaderV2, TileService. Closes LF-2 by
forwarding HttpContext.RequestAborted from GetTileByLatLon into the
downloader. appsettings.json gains the 8 new keys at default values.

Tests: 141 / 141 unit + 5 / 5 smoke green. New ConfigDefaultsTests pins
defaults to original literals; new TileService unit test asserts CT
identity from caller to downloader (AZ-371 AC-3).
