Three coordinated fixes to make in-app APK download work end-to-end:
1. version-service/main.ts: serve uploaded files as static assets via
NestExpressApplication.useStaticAssets('/data/versions', prefix:
'/downloads/versions'), so GET /downloads/versions/{platform}/{file}
returns the actual APK stored in the Docker volume.
2. kong.yml: add /downloads/versions route to Kong so requests from
the Flutter app can reach version-service through the API gateway.
Previously only /api/v1/versions and /api/app/version were routed;
the download URL returned by the check endpoint was unreachable (404).
3. download_manager.dart: skip SHA-256 verification when sha256Expected
is empty string. The check endpoint always returns sha256:"" because
version-service doesn't store file hashes. The previous code compared
actual_hash == "" which always failed, causing the downloaded file to
be deleted after a successful download.

Add verbose debugPrint logs throughout VersionChecker to diagnose why
app update check isn't triggering:
- Log apiBaseUrl and full request URL + query params before the request
- Log response status code and raw response body
- Log explicit needUpdate=true/false with version details
- Log version code comparison (server versionCode vs local buildNumber)
- Add stack trace to all catch blocks for better error diagnosis
