feat(desktop): mark cut-plan issues on the plate and trim the inspection panel

Plan Cutting findings dropped the checker's geometry, so selecting one could only
zoom to part extents, and overlap-blocked plates (no preview) did nothing at all.
Findings now keep the check's world-coordinate witness (overlap regions, rapid,
contacts); selecting a row draws it with the Validate Nest overlay, on the proposal
or a blocked plate's live sheet. The witness is excluded from finding equality so
repeated search rejections still collapse to one finding.

The side panel's scrolling report was a wall of text operators skipped. It is now
a colored outcome line, one line for the shown plate, and one remedy or marker
hint above the issue grid, with secondary detail moved to tooltips.
