Remove legacy code from Model Manager

- Removed legacyMode flag from ServerConfig
- Removed resetToLegacyDirectories() method and its implementation
- Removed legacy scanning mode from ModelManager
- Simplified configureFromServerConfig() to always use explicit directories
- Updated getModelTypeDirectory() to remove legacy path construction
- Updated determineModelType() to remove legacy directory structure checks
- All legacy-related comments and implementation removed
- Build compilation successful with no warnings or errors
