Moving first before going to safe travel height

[Bastel Baus]

traveling to beginning of a path and passing exclusion areas

a) tool is moved before lifting → should be wise versa → major

• happens probably also at other positions, to be checked over the code.

b) overwriting global move_z might lead to lower z_height. I would propose to go for max(move_z, travel[0]) → proposal
