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).
