[AZ-364] [AZ-360] Refactor C11+C08: decompose RouteProcessingService

Extracts RouteRegionMatcher, RouteCsvWriter, RouteSummaryWriter,
RouteImageRenderer, TilesZipBuilder, RegionFileCleaner from the
~750-LOC RouteProcessingService god-class. Moves TileInfo to its
own file as a sealed record. Replaces IServiceProvider scope-
locator with a direct IRegionService injection (folds AZ-360 / C08).
Updates DI registration and tests.

Tests: 133 / 133 unit + 5 / 5 smoke green; integration suite exit 0.
Pixel-equivalent stitched route image and byte-equivalent CSV /
summary / ZIP outputs verified through the smoke run.
