Sebastian Krüger e1c19ffcb3 feat: implement Phase 12.1 - Project Management with IndexedDB
Added complete project save/load system using IndexedDB:

**New Files:**
- `lib/storage/db.ts` - IndexedDB database schema and operations
  - ProjectMetadata interface for project metadata
  - SerializedAudioBuffer and SerializedTrack for storage
  - Database initialization with projects object store
  - Audio buffer serialization/deserialization functions
  - CRUD operations for projects

- `lib/storage/projects.ts` - High-level project management service
  - Save/load project state with tracks and settings
  - List all projects sorted by last updated
  - Delete and duplicate project operations
  - Track serialization with proper type conversions
  - Audio buffer and effect chain handling

- `components/dialogs/ProjectsDialog.tsx` - Project list UI
  - Grid view of all projects with metadata
  - Project actions: Open, Duplicate, Delete
  - Create new project button
  - Empty state with call-to-action
  - Confirmation dialog for deletions

**Key Features:**
- IndexedDB stores complete project state (tracks, audio buffers, settings)
- Efficient serialization of AudioBuffer channel data
- Preserves all track properties (effects, automation, volume, pan)
- Sample rate and duration tracking
- Created/updated timestamps
- Type-safe with full TypeScript support
