Add the foundation for audio processing filters, mirroring the existing picture filter/postprocessing template system: - AudioFilter base class, AudioFilterRegistry, AudioFilterOptionDef - AudioProcessingTemplate dataclass + SQLite-backed store - audio_filter_template meta-filter with recursive resolution - Full REST API: CRUD templates + filter registry discovery - Dependency injection wired in dependencies.py and main.py
