Add web-based config interface via ttyd

- Install ttyd in Docker image for browser-based TUI access
- Create docker-entrypoint.sh to run ttyd + bot with auto-restart
- Expose port 7681 for web config access
- Update docker-compose.yml with proper configuration

Access config at http://localhost:7681 after starting container
