1. Equipment slots: armor (object_class=2) now renders in ALL matching
slots via bitmask, not just the first. E.g. a chest piece covering
upper arm + chest + abdomen appears in all 3 slots. Non-armor items
still use first-match. Matches v1's exact logic.
2. Pack fill bars: changed from horizontal-below to vertical-right of
each pack icon. 4px wide bar with fill from bottom, color-coded:
green <70%, orange 70-90%, red >90%.
3. Burden: removed garbled percentage (was dividing by 10). Now shows
"Burden" label with total burden in tooltip. Bar shows 50% as
placeholder until character_stats provides encumbrance_capacity.
4. PackIcon component: reusable for main backpack + sub-packs, shows
game icon + vertical fill bar + green active glow + gold ▶ arrow.
