feat(database): Implement comprehensive database service layer

Browse Source 
Implemented database service layer with CRUD operations for all models:

- AnimeSeriesService: Create, read, update, delete, search anime series
- EpisodeService: Episode management and download tracking
- DownloadQueueService: Priority-based queue with status tracking
- UserSessionService: Session management with JWT support

Features:
- Repository pattern for clean separation of concerns
- Full async/await support for non-blocking operations
- Comprehensive type hints and docstrings
- Transaction management via FastAPI dependency injection
- Priority queue ordering (HIGH > NORMAL > LOW)
- Automatic timestamp management
- Cascade delete support

Testing:
- 22 comprehensive unit tests with 100% pass rate
- In-memory SQLite for isolated testing
- All CRUD operations tested

Documentation:
- Enhanced database README with service examples
- Integration examples in examples.py
- Updated infrastructure.md with service details
- Migration utilities for schema management

Files:
- src/server/database/service.py (968 lines)
- src/server/database/examples.py (467 lines)
- tests/unit/test_database_service.py (22 tests)
- src/server/database/migrations.py (enhanced)

- **Migration**: Schema versioning with Alembic
- **Testing**: Easy to test with in-memory database
### Database Service Layer (October 2025)
Implemented comprehensive service layer for database CRUD operations.
**File**: `src/server/database/service.py`
**Services**:
- `AnimeSeriesService`: CRUD operations for anime series
- `EpisodeService`: Episode management and download tracking
- `DownloadQueueService`: Queue management with priority and status
- `UserSessionService`: Session management and authentication
**Key Features**:
- Repository pattern for clean separation of concerns
- Type-safe operations with comprehensive type hints
- Async support for all database operations
- Transaction management via FastAPI dependency injection
- Comprehensive error handling and logging
- Search and filtering capabilities
- Pagination support for large datasets
- Batch operations for performance
**AnimeSeriesService Operations**:
- Create series with metadata and provider information
- Retrieve by ID, key, or search query
- Update series attributes
- Delete series with cascade to episodes and queue items
- List all series with pagination and eager loading options
**EpisodeService Operations**:
- Create episodes for series
- Retrieve episodes by series, season, or specific episode
- Mark episodes as downloaded with file metadata
- Delete episodes
**DownloadQueueService Operations**:
- Add items to queue with priority levels (LOW, NORMAL, HIGH)
- Retrieve pending, active, or all queue items
- Update download status (PENDING, DOWNLOADING, COMPLETED, FAILED, etc.)
- Update download progress (percentage, bytes, speed)
- Clear completed downloads
- Retry failed downloads with max retry limits
- Automatic timestamp management (started_at, completed_at)
**UserSessionService Operations**:
- Create authentication sessions with JWT tokens
- Retrieve sessions by session ID
- Get active sessions with expiry checking
- Update last activity timestamp
- Revoke sessions for logout
- Cleanup expired sessions automatically
**Testing**:
- Comprehensive test suite with 22 test cases
- In-memory SQLite for isolated testing
- All CRUD operations tested
- Edge cases and error conditions covered
- 100% test pass rate
**Integration**:
- Exported via database package `__init__.py`
- Used by API endpoints via dependency injection
- Compatible with existing database models
- Follows project coding standards (PEP 8, type hints, docstrings)
**Database Migrations** (`src/server/database/migrations.py`):
- Simple schema initialization via SQLAlchemy create_all
- Schema version checking utility
- Documentation for Alembic integration
- Production-ready migration strategy outlined

# Mark as downloaded
updated = await EpisodeService.mark_downloaded(
db,
episode_id,

### UserSessionService
```python

from datetime import datetime, timedelta
# Create session
expires_at = datetime.utcnow() + timedelta(hours=24)
session = await UserSessionService.create(
db,

# Get active sessions

Database Migration Information
==============================
Current Strategy: SQLAlchemy create_all()
- Automatically creates tables on startup
- Suitable for development and single-instance deployments
- Schema changes require manual handling
For Production Migrations (Alembic):
====================================
1. Initialize Alembic:
alembic init alembic
2. Configure alembic/env.py:
- Import Base from src.server.database.base
- Set target_metadata = Base.metadata
3. Configure alembic.ini:
- Set sqlalchemy.url to your database URL
4. Generate initial migration:
alembic revision --autogenerate -m "Initial schema"
5. Apply migrations:
alembic upgrade head
6. For future changes:
- Modify models in src/server/database/models.py
- Generate migration: alembic revision --autogenerate -m "Description"
- Review generated migration in alembic/versions/
- Apply: alembic upgrade head
Benefits of Alembic:
- Version control for database schema
- Automatic migration generation from model changes
- Rollback support with downgrade scripts
- Multi-instance deployment support
- Safe schema changes in production

# Future Alembic Integration

#
# 1. Install Alembic (already in requirements.txt):
# pip install alembic
