Replace 'Read Serial' button with 'Open UART' that opens a new UART Monitor window (CTkToplevel) with: - Title bar with status indicator (● connecting/ready/monitoring/error) - Port info display + Start/Stop/Clear buttons - Large scrollable log area (CTkTextbox) with monospace font - Auto-scroll to bottom, line counter in status bar - Boot info parsing (IP, version) shown as [BOOT] prefix - Background serial monitoring via UartMonitor class UART unavailable handling: - On init, tries to open serial port in background thread - If port can't open → shows 'UART 不可用' state with error message - If port opens → shows 'Ready', user clicks Start to begin monitoring Window features: - Modal (grab_set) — focus stays on monitor window - Clean up UartMonitor on close (WM_DELETE_WINDOW handler) - Thread-safe UI updates via after(0, ...) - Reuses existing UartMonitor from serial_monitor.py
