fix: force redisplay before position queries to fix initial image placement

After org-toggle-inline-images creates overlays with multi-line display
properties, posn-at-point still sees pre-overlay layout because Emacs
hasn't recomputed pixel positions yet. This caused images to appear ~4
rows too low on initial render (scrolling would fix it).

Adding (redisplay t) at the start of kitty-gfx--refresh forces a full
layout recomputation so position queries return correct values immediately.

Also includes: simplified column calculation using window-body-edges,
stderr suppression in call-process, debug state inspection commands,
and ImageMagick binary preference fixes.
