Add sketches with measures from KiCad and fix PCB reference

[JeroMul]

I added a coordinate system attached to the center of Binder 25.11, so everything is now positioned relative to the same reference
Sketches have been created based on measurements from KiCad project to reflect fixation and cutting holes positions

Sorry for the delay, my FreeCAD box is at work…

This is a nice and appreciated addition, but I have a couple remarks. :-)

• We should define a naming scheme. In SketchCutHolesLeftOscar26.01.1, Sketch is already known by the element type, Oscar26.01.1 belongs to the versioning system — so I’d rather use something very straight-forward such as pre-cut dashes and screw holes for these elements (lowercase, with spaces?).
• I’m surprised you’ve used a key rather than the axis origin to position these dashes and holes, is there a reason for that?

In fact I wonder why you made one sketch for every kind of cuts in the PCB? Is there a technical reason not to use a single cuts sketch for the pre-cut dashes and screw holes?

The sketches reflect a state of another file in another git (the kicad file), that have been used to create real pcbs on the field with that name. I made them to check the current state and verify dimensions and symetry.
I created the left cut holes first and symetrised them, then created the right cut holes on top of that, and can see that they do not match exactly.
Same for the center cut holes, they are not exactly centered.
Based on these information, we could create a good single sketch that fits the already existing boards
