Fix CSV flag fields integration test

- Rename test_flag_fields_are_numeric to test_flag_fields_are_formatted
- Update test to expect formatted text values (IDLE, ANGLE_MODE, etc.) instead of raw numeric values
- Add proper validation for failsafePhase, flightModeFlags, and stateFlags formatted output
- Align test expectations with actual CSV export behavior that outputs human-readable flag names
