torlando-tech b6b34603ec fix: add BLE write synchronization to prevent dropped commands 
Android BLE is asynchronous - writeCharacteristic() only queues the write.
Without waiting for onCharacteristicWrite() callback, subsequent writes
are silently dropped by the BLE stack.

Changes:
- Add CountDownLatch-based synchronization in KotlinRNodeBridge
- Each BLE write now waits for callback confirmation before proceeding
- Add small delays in Python for framebuffer writes (defensive)

This fixes reliability issues with RNode framebuffer commands on BLE.
Note: T114 still won't show framebuffer due to upstream firmware bug
(bt_ssp_pin set at startup, never cleared).
