Improve UI of movement panel

[blaggacao]

This PR optimizes the CNC Movement Panel such that when run on Mobile, users are less likely to achieve either of these adverse outcomes:

• Accidentially click on a "Set" button because it is right at the edge of the cell phone screen, close to where you typically hold and support you mobile phone

• Accidentially go to work zero for the same reason breaking your toolbit on its way (or alternatively triggering an emergency stop, loosing homing et al)
• Accidentially set an axis instead of triggering a jog button because the jog button is way too close to the next axis' set (or home) buttons

This also moves the less important calibration options a bit out of the prime screen estate further down where they are still easy to find but defer to the more important options.

After

Granted, this optimizes for right-handers, about approx. 85% to 90% of all people.
