feat: profession crafting improvements and combat sound fixes

- Suppress spell sounds for profession/tradeskill spells (crafting is silent)
- Add craft quantity UI to profession trainer: recipe selector, quantity
  input, Create button, and Stop button for active queue
- Known recipes show Create button to cast directly from trainer window
- Craft queue auto-recasts on CREATE_ITEM completion, cancels on failure
- Fix missing combat sounds: player spell impacts on enemies, enemy spell
  cast sounds targeting player, instant melee ability weapon sounds
