fix(plymouth): recolor splash art from the palette for contrast

Browse Source 
The shipped boot art was a fixed navy that vanished against dark theme
bases. Recolor each element from theme-state.json at build time (flat
fill, alpha preserved): foreground glyphs (logo, padlock, password dots)
→ text, the field/track boxes (entry, progress_box) → surface, and the
progress fill → accent. text/surface both contrast with base in either
polarity, so the splash now reads on light and dark themes alike.

Adds imagemagick as a build-time input to the theme derivation. Like the
background tint, this follows the theme as of the last system rebuild.
