Fix shutdown hangs, bank bag icons/drag-drop, loading screen progress, and login spawn

- Fix shutdown hang: skip vmaDestroyAllocator (walked thousands of allocations),
  replace unsafe pthread_timedjoin_np with plain join + early-exit checks in workers
- Bank window: full icon rendering, click-and-hold pickup (0.10s), drag-drop for
  all bank slots including bank bag equip slots, same-slot drop detection
- Loading screen: process one tile per frame for live progress updates
- Camera reset: trust server position in online mode to avoid spawning under WMOs
- Fix PLAYER_BYTES/PLAYER_BYTES_2 field indices, preserve purchasedBankBagSlots
  across inventory rebuilds, fix bank slot purchase result codes
