fix(gtk): bypass fragile SVG recoloring with static palette assets
Some checks failed
Check / eval (push) Failing after 1m55s

Browse Source 
GTK's -gtk-recolor proved too fragile across different contexts, failing
to substitute the foreground color even when the SVG path used #000000.
Instead, we now generate two statically colored SVGs (normal + hover)
directly from the Nix palette hex codes, bypassing GTK's SVG recoloring
engine entirely.
