feat(events): add 16 event scene background illustrations
16 event backgrounds at 1592x848 DXT1 DDS covering all scene
types: 3 noble interiors (court, ball, private_chamber), 3
institutional interiors (temple, dungeon, ruins), 1 noble arena
(fighting_pit), 4 skaa/underclass (streets, plantation,
underground, market), and 5 exteriors (wilderness, battlefield,
mists, ashmount_close, clear_night). Noble interiors use bright
marble and colored fabrics to contrast wealth against ash-choked
exteriors. Fighting pit designed as noble spectacle arena per
Mistborn lore.
