Fix: Add clear instructions for manual Z-offset calibration

CARTOGRAPHER_SCAN_CALIBRATE requires manual interaction when no
calibration exists. The macro was continuing without waiting for
user input, resulting in incorrect Z values (395mm!).

Updated macros:
- CALIBRATE_PROBE: Added detailed instructions for TESTZ/ACCEPT/ABORT
- CALIBRATE_Z_OFFSET: Added step-by-step console instructions

Users now see clear guidance:
- TESTZ Z=0.01 → Move nozzle DOWN (closer to bed)
- TESTZ Z=-0.01 → Move nozzle UP (away from bed)
- ACCEPT → Finish calibration
- ABORT → Cancel

Note: QUICK_TOUCH uses CARTOGRAPHER_TOUCH which works automatically.
