Add callback management API/UI and theme support

- Add callback CRUD endpoints (create, update, delete, list)
- Add callback management UI with all 11 callback events support
- Add light/dark theme switcher with localStorage persistence
- Improve button styling (wider buttons, simplified text)
- Extend ConfigManager with callback operations

 ## Features
 
+- **Built-in Web UI** for real-time media control and monitoring
 - Control any media player via system-wide media transport controls
 - Play/Pause/Stop/Next/Previous track
 - Volume control and mute
 - Seek within tracks
 - Get current track info (title, artist, album, artwork)
+- WebSocket support for real-time updates
 - Token-based authentication
 - Cross-platform support
 
+## Web UI
+
+The media server includes a built-in web interface for controlling and monitoring media playback.
+
+### Features
+
+- **Real-time status updates** via WebSocket connection
+- **Album artwork display** with automatic updates
+- **Playback controls** - Play, pause, next, previous
+- **Volume control** with mute toggle
+- **Seekable progress bar** - Click to jump to any position
+- **Connection status indicator** - Know when you're connected
+- **Token authentication** - Saved in browser localStorage
+- **Responsive design** - Works on desktop and mobile
+- **Dark theme** - Easy on the eyes
+
+### Accessing the Web UI
+
+1. Start the media server:
+   ```bash
+   python -m media_server.main
+   ```
+
+2. Open your browser and navigate to:
+   ```
+   http://localhost:8765/
+   ```
+
+3. Enter your API token when prompted (get it with `media-server --show-token`)
+
+4. Start playing media in any supported player and watch the UI update in real-time!
+
+### Remote Access
+
+To access the Web UI from other devices on your network:
+
+1. Find your computer's IP address (e.g., `192.168.1.100`)
+2. Navigate to `http://192.168.1.100:8765/` from any device on the same network
+3. Enter your API token
+
+**Security Note:** For remote access over the internet, use a reverse proxy with HTTPS (nginx, Caddy) to encrypt traffic.

+### Authentication
+
+The media server supports multiple API tokens with friendly labels. This allows you to:
+- Issue different tokens for different clients (Home Assistant, mobile apps, web UI, etc.)
+- Identify which client is making requests in the server logs
+- Revoke individual tokens without affecting other clients
+
+**Token labels** appear in all server logs, making it easy to track and debug client connections:
