v3.2.1 - rTorrent HTTPS, Self-Hosted Assets & Script Debugging

✨ Added

• rTorrent HTTPS Support - Connect to rTorrent XML-RPC endpoints over HTTPS/SSL, matching qBittorrent, Deluge, and Transmission. Configurable via Settings UI, RTORRENT_USE_SSL env var, or config.json
• Self-Hosted Country Flags - Country flag SVGs are now bundled locally instead of loading from an external CDN, eliminating Content Security Policy issues and external dependencies
• Self-Hosted Chart.js - Chart.js is now bundled locally instead of loading from jsdelivr CDN, removing the last external script dependency
• Event Script CRLF Detection - Scripts with Windows line endings (CRLF) are detected before execution with a clear warning and fix command in logs

🐛 Fixed

• Event Script Error Logging - stderr output is now always logged regardless of exit code, and stdout is included on failures for easier debugging
• Settings Auto-Scroll on Mobile - Fixed section auto-scroll not working on mobile when expanding sections that stretch the page content

🔒 Security

• Tighter CSP - Removed cdn.jsdelivr.net from script-src Content Security Policy directive — all assets are now self-hosted
