Implement servo bidirectional mapping (C-first vectors)

Added servo_bidir() and servo_rc_car() to input_mapping.rs, matching C
firmware setInput() servo paths. Wired into process_input() for both
servo bidir (speed-gated direction flip with dead band) and servo RC-car
(brake-and-reverse with return-to-center handshake).

Key fix: servo_rc_car return_to_center path now computes throttle AND
flips direction in the same pass (C falls through to map after flip).

Golden vectors captured from C harness first:
- servo_bidir.txt: direction flip, dead band, same-direction throttle
- servo_rc_car_bidir.txt: brake, dead band clear, direction flip
