Rework the M-Archy splash: scale the skull to ~42% of screen height and
centre it instead of filling the screen, then draw the latest 3 boot-log
lines beneath it (fed by both the status and display-message callbacks).
Drops the imagemagick-generated dot.png throbber and its refresh loop.
Render the logo at 600px (down from 1920px) since it is no longer
full-screen, and only pull in imagemagick for the transparent-placeholder
fallback. migrate-to-lightdm purges the stale dot.png before re-running the
module so upgraded installs end up byte-clean. Update docs and module
labels ("skull logo + boot-log tail"), and simplify bg-skull.svg.
