FIX: Add missing u_dot parameter to direct triggerfunc calls

Direct calls to parachute.triggerfunc() were missing the u_dot parameter,
causing TypeError in unit tests. Added u_dot=None to non-overshoot and
overshoot trigger evaluation paths where u_dot is not computed.

Fixes test failures in:
- tests/unit/simulation/test_flight.py
- tests/unit/test_utilities.py
- tests/unit/test_rail_buttons_bending_moments.py
- tests/unit/test_flight_data_exporter.py
