fix: scrub remaining Mamba references in can_bridge and e2e test protocol files
- balance_protocol.py: Mamba→Orin / Mamba→VESC comments → ESP32-S3 BALANCE - can_bridge_node.py: docstring and inline comments - __init__.py: package description - protocol_defs.py: all Mamba references in docstring and comments - test_fc_vesc_broadcast.py, test_drive_command.py: test comments Zero Mamba/STM32F722/BlackPill/stm32_protocol/mamba_protocol references now exist outside legacy/stm32/.

### Why a Drone FC?
|
||||
The F745 board was a premium STM32 dev board (legacy; now replaced by ESP32 BALANCE) with a high-quality IMU (MPU-6000) already soldered on, proper voltage regulation, and multiple UARTs broken out. We write a lean custom balance firmware (~50 lines of C).
