Survey (GRID) GUI add automatically do set speed command as it's tuned, same as cam trigg dist

Actually, when using Survey(Grid) , we can through GUI set ground speed for tune timing between each photos, but when we accept, automated mission generated from it no contain do set speed before or after do set cam trigg dist command.

Also GUI auto generate mission with another error, it put do set cam trig dist after takeoff and no after first waypoint.

Also for more security, could you please change land command generated at the end by RTL command ?

Start by tracing the Survey(Grid) GUI mission-generation path, since no specific file or test is named. Compare generated command ordering and verify that tuned speed and camera-trigger distance are included in the intended positions, with RTL replacing the final land command when the requested behavior is complete.
