FlightPlanner: Simultaneous Display of Mission, Geofence, and Rally Points in PLAN Screen

[tatsuy]

simultaneous display of all elements—missions, fences, and rally points

Changes:

• Maintain the current dropdown menu for selecting the primary editable item ("MISSION", "FENCE", or "RALLY").
• The selected item from the dropdown menu would be displayed in an editable mode, allowing users to add, remove, or modify points as currently possible.
• Items not selected in the dropdown menu would be displayed in a read-only mode. This would allow users to see all elements (mission waypoints, geofence boundaries, and rally points) overlaid on the map simultaneously, but only edit the item type they have selected from the dropdown menu.

Resolved these issues #3300 and #3305.

It works only when you are connected to a vehicle and changes are uploaded to the vehicle. Not working in offline mode.

Implementing the logic for offline mode will require additional work, and it seems it might take some time to properly address. Therefore, I've decided to split the PRs. This PR addresses the functionality only when connected to a vehicle. The offline mode functionality will be tackled in a future update.

@EosBandi I've updated the implementation to support simultaneous display even when not connected to a vehicle, addressing the offline mode functionality. Feedback is always welcome!

@meee1 @EosBandi I want to use this feature in the next lastest release. Could someone test this for merging?
