Fixes
- Static theme blinks to USB standby symbol every ~30 s: No frames were sent after the initial theme load when no dynamic overlay elements triggered a re-render. A keepalive fires every ~20 s to resend the current frame and prevent USB timeout
- Device polled every 15 s while connected:
find_lcd_devices()ran a full sysfs USB scan on every poll tick regardless of connection state. The scan now only runs when no device is connected
