index-cal cfg updates & fixes

[3DPrintDemon]

Fix camera cal macro names, move cal test inboard, improve load cell cal macro, add manual tool remove & toolhead state resets.

• Camera calibration names with numerics in the middle always fail
  

• Changing the names to written numbers fixes this.

• Move testing inbound slightly for peace of mind.

• Improve load cell calibration macro

• Add manual tool remove & set state macro

• Add manual toolhead reset state macro

Feel free to edit or discard what you wish.

I found an issue in CAL_THREE_SAVE_XY_OFFSET while testing the camera calibration macros on a six-tool INDX setup.

At this point the nozzle has already been physically centered over the camera, and off_x / off_y represent the displacement from the saved T0 camera position. Applying the offset with MOVE=1 causes an additional physical move by the same vector after the values have been saved.

In testing, the resulting physical position was:

camera_position + 2 * calculated_offset

This affects any tool with a non-zero XY offset. A subsequent move back to the camera coordinates can hide the initial displacement, but it adds an unnecessary round trip and can expose motion or tool-seating repeatability error.

Removing MOVE=1 keeps the already-centered nozzle physically stationary while updating the coordinate system:

SET_GCODE_OFFSET X={"%.3f"|format(off_x)} Y={"%.3f"|format(off_y)}

The MOVE=1 in CAL_TWO_PREP_TOOL_CAL, where existing offsets are cleared before moving to the camera position, should remain unchanged.

After removing it, saving the offset produced no physical movement, and the resulting G-code position matched the saved camera reference within 0.0004 mm.
