Add feedback for limit orientation of TTool detection

[9and3]

If too steep the camera angle when pointing and detecting the Toolhead can risult in a false pose detection of the tool. We should add a feedback visuals to avoid this and place the camera more or less parallel to the e.g. blades.

hint: ⚡ one idea could be to calculate the surface of the highlighted tool and estimate a threshold percentage on the number of pixels.
