Consolidate dev -> omarchy-shell migration; drop premature widget removal

Replace the mako-only migration with a single "complete the flip"
migration that handles everything needed to bring a dev-channel user
onto omarchy-shell:

  - install quickshell if it isn't already on the box
  - stop and uninstall mako; pacman -Rns deletes the .service unit too,
    so D-Bus activation can't conjure it back into existence
  - stop and uninstall waybar with the same uninstall-not-mask approach
  - move ~/.config/{mako,waybar} aside (timestamped backup) rather than
    rm -rf, so anyone with hand-tuned rules can mine them
  - clear the stale toggle-state markers
  - call omarchy-restart-shell so the bar and notification daemon come
    up mid-session without a relog

Drop migrations/1778715864.sh: shell.json hasn't shipped to any user
yet, so a migration removing widgets nobody has is dead code.
