refactor: extract findOnUseSpellId helper, add warden hash comment

Browse source 
- spell_handler: extract duplicated item on-use spell lookup into
  findOnUseSpellId() — was copy-pasted in useItemBySlot and useItemInBag
- warden_handler: add why-comment explaining the door model HMAC-SHA1
  hash table (wall-hack detection for unmodified 3.3.5a client data)
