Add four Star Trek / Lower Decks pages with a 3D printer red alert

LCARS ship status, the Cerritos duty roster from the agenda, a warp core
driven by solar power with Rutherford's advice, and a captain's log under
a viewscreen. Original pixel art in tools/trek_sprites.py.

When the 3D printer (Moonraker current_print_state, `printer`
substitution) is paused or in error, the panel jumps to LCARS Status in
red alert and holds the rotation until it carries on.
