Battery reserve safeguards and layered 3D missions

Calculates the estimated remaining battery for Waypoint, 2D, 3D, and POI missions from the selected drone’s stored maximum flight time
Shows a warning whenever a completed mission is expected to leave less than the planned 20 percent reserve
Requires explicit confirmation before exporting a mission below the battery reserve
Keeps 3D mapping as one saved mission and one export with one total distance and estimated flight time
Generates one nadir pass and four oblique passes on optimized grids separated by 90 degrees and opposite traversal directions
Adds five color-coded 3D flight layers that are visible together by default and individually switchable
Places Mission save immediately above a full-width orange drone-mission export action
Shows the active language only once and moves My profile into the dashboard’s second row
