Pull request overview

This PR adds a total flight time timer to the status bar that tracks how long the aircraft has been flying during the current session. The implementation uses a new Redux middleware to monitor the armed/flying state and increment a timer every second while the aircraft is in flight.

Changes:

• Moved VFR_HUD message from page-specific to global listeners for consistent telemetry access
• Added new Redux middleware to track flight time with 1-second intervals
• Added status bar UI component displaying flight time in MM:SS format
