feat: Complete stub services with real implementations and graceful not-configured responses

- ChangelogService: inject PlatformChangelog repo, query with findAndCount(skip/take), return actual data
- ChangelogModule: add TypeOrmModule.forFeature([PlatformChangelog])
- MapsService: add uploadMap() — SHA-256 checksum, storage path, full entity save
- MapsController: add POST /maps/upload with FileInterceptor, map.manage permission, @UploadedFile
- AuthService: replace console.log stubs with Logger; forgotPassword returns 200 with clear message; resetPassword throws NotImplementedException
- PluginsService: searchUmod returns { results: [], message: 'not yet configured' } instead of bare []
- SteamService: add Logger.warn on every stub path (checkForceWipe, getPlayerSummary)
- SettingsService: add Logger; both Cloudflare DNS stubs emit Logger.warn before DB save
- MigrationService: add Logger; exportConfig logs warning + returns note field; importConfig throws NotImplementedException
- Install @types/multer dev dependency for Express.Multer.File type support
