root 1fe7392063 feat: Complete Sonarr integration with security enhancements
This commit adds comprehensive Sonarr webhook integration and implements
critical security improvements identified in code review.

## Sonarr Integration
- Full webhook support for Grab, Download, Rename, Delete, and Test events
- HMAC SHA256 signature verification for webhook authentication
- Series mapping system (Sonarr TVDB ID → Anime Provider URL)
- 11 new API endpoints for configuration, mappings, search, and downloads
- Comprehensive test suite (31 tests, all passing)
- Complete documentation in docs/SONARR_INTEGRATION.md

## Security Enhancements
- CORS restricted to specific origins (user's IP: 192.168.1.204:3000)
- Path traversal prevention via sanitize_filename() and is_safe_filename()
- Structured logging infrastructure (replaced all print() statements)
- Environment-based configuration with .env support
- Filename sanitization prevents malicious path attacks

## New Features
- Lpayer and Sibnet downloader support
- Kitsu API integration for anime metadata
- Recommendation engine based on download history
- Latest releases endpoint for new anime
- Modular web interface with component-based templates

## Configuration
- Centralized settings via app/config.py with pydantic-settings
- Sonarr config auto-created in config/ directory
- Example configurations provided for easy setup

## Tests
- 31 Sonarr integration tests (23 functionality + 9 security)
- 100+ tests passing in core test files
- Security utilities fully tested

## Documentation
- Updated CLAUDE.md with Sonarr and testing info
- Added IMPROVEMENTS_2024-01-24.md analysis
- Added SONARR_IMPLEMENTATION.md technical summary
