Turn auto trim into a fly-by-wire flight computer

Pitch input becomes a rate command; the computer measures the pitching torque
without its own surfaces (airframe stability, thrust line, weight offset) and
cancels it with dynamic inversion, so relaxed-stability craft stay controllable.
Replaces trimAuthority with flightComputer* config values.
