feat: extend /use command to support bag/slot notation and equip slot numbers

Browse source 
Adds WoW macro-standard /use argument forms alongside the existing
item-name search:

- /use 0 <slot>   — backpack slot N (1-based, bag 0)
- /use 1-4 <slot> — equipped bag slot N (1-based bag index)
- /use <N>        — equip slot N (1-based, e.g. /use 16 = main hand)

These are the standard forms used in macros like:
  #showtooltip
  /use 13          (trinket 1)
  /cast Arcane Blast
