feat: show spell icon on macro buttons via #showtooltip directive

Browse source 
- getMacroShowtooltipArg() parses the #showtooltip [SpellName] directive
- Action bar macro buttons now display the named spell's icon when
  #showtooltip SpellName is present at the top of the macro body
- For bare #showtooltip (no argument), derives the icon from the first
  /cast line in the macro (stripping conditionals and rank suffixes)
- Falls back to "Macro" text label only when no spell can be resolved
