Mirror of AZ-794 (inventory z/x/y rename). RequestRegionRequest.cs renames C#
props Latitude→Lat / Longitude→Lon and adds [JsonPropertyName("lat"/"lon")] so
the wire format is unambiguous under the AZ-795 strict-parsing stack
(UnmappedMemberHandling.Disallow → legacy {"latitude":..,"longitude":..} now
returns HTTP 400 instead of silently coercing).
Updates all in-repo consumers: API handler (Program.cs), integration tests
(Models.cs, RegionTests.cs, IdempotentPostTests.cs, SecurityTests.cs), the
performance harness (run-performance-tests.sh PT-03/04/05/07), and module
docs (common_dtos.md, api_program.md; system-flows.md F2 already used
lat/lon). New RegionFieldRenameTests.cs covers AC-4 both directions (new
format → 200, legacy format → 400). Smoke green; no regressions.
region-request.md contract doc not bumped here — AZ-808 publishes v1.0.0
directly with the post-rename names per AZ-812 coordination clause.
Batch 01 of cycle 8. PASS_WITH_WARNINGS (one Low DRY finding for follow-up
test-helper consolidation; details in
_docs/03_implementation/reviews/batch_01_cycle8_review.md).

Move 5 cross-component DTOs (GetSatelliteTilesResponse, SatelliteTile,
SaveResult, DownloadTileResponse, RequestRegionRequest) to
SatelliteProvider.Common/DTO/. Keep UploadImageRequest in the API
project under SatelliteProvider.Api.DTOs (IFormFile depends on
Microsoft.AspNetCore.Http; pulling it into Common would force an
ASP.NET framework reference into the foundation layer and break the
module-layout "Common: Imports from: (none)" invariant). Move
ParameterDescriptionFilter to SatelliteProvider.Api.Swagger.
Program.cs shrinks from 366 to 257 lines and now contains only
endpoint wiring (AC-1). JSON wire shape and Swagger schema names are
preserved (AC-2). 84 unit + full integration suite green (AC-3).
