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.

Flutter VersionChecker was calling GET /api/app/version/check but this
endpoint didn't exist — only the admin CRUD /api/v1/versions was there.
New: AppVersionCheckController (@Controller('api/app/version'))
GET /api/app/version/check?platform=android¤t_version_code=N
- Finds latest enabled version for the platform (highest buildNumber)
- Returns { needUpdate: false } when already up to date
- Returns full VersionInfo payload when update is available
Response fields match Flutter VersionInfo.fromJson exactly:
needUpdate, version, versionCode, downloadUrl, fileSize,
fileSizeFriendly (computed), sha256 (empty — not stored),
forceUpdate, updateLog, releaseDate
Also: AppVersionRepository.findLatestEnabled(platform) — queries all
enabled versions for platform, picks the one with the highest buildNumber
(parsed as int, robust against varchar storage).

The entrypoint.sh expects dist/services/${SERVICE_NAME}/src/main, but
nest build with inline TypeORM config produces dist/main directly.
Using DatabaseModule from @it0/database forces tsc to emit the nested
path structure (since it references shared packages), matching the
entrypoint path convention used by all other services.
Also gains SnakeNamingStrategy and autoLoadEntities from the shared module.
