Correct XYZ after obtaining plan_bed_level_matrix

The current position needs to be updated by using the inverse
`plan_bed_level_matrix` on X, Y, and Z. All moves in the planner are
transformed by the `plan_bed_level_matrix` from this point forward.

Raise when not retracting

Code to raise the probe before retraction is good, but the code should
always raise the probe, not just when retracting

Fix EXTRUDER_OFFSET compiler error

Correct the comment about M206

Fix LCD click

fully separated from Z_MIN or Z_MAX.
Fixed a documentation error in sanity checks. Servos start at 0 not 1.
