Add unit tests for flight event labeling

[Sanjana-Siddani]

Description

The project uses rules in label_generator.py to assign flight-event labels. These rules do not currently have automated unit tests.

Create tests to verify that representative telemetry values generate the expected labels.

Tasks

• Set up pytest for the inference folder.

• Create a test file for FlightEventLabeler.

• Add at least one test for each event:
  TAXI
  TAKEOFF
  CRUISE
  APPROACH
  LANDING
  TURN_LEFT
  TURN_RIGHT
  HIGH_SPEED
  LOW_SPEED
  HIGH_ALTITUDE
  LOW_ALTITUDE
  HIGH_G_FORCE
  NORMAL_FLIGHT

• Test heading wraparound, such as 359° to 1°.

• Test values at important boundaries.

• Add instructions for running the tests.

Acceptance Criteria

• All 13 expected event labels are tested.
• Heading wraparound is tested.
• At least three threshold-boundary cases are tested.
• Tests run with one documented command.
• All tests pass locally.
• Existing production code is not changed unless a bug is found.
• Any discovered bug is documented separately.
