Release 4.2: spell IDs, base-health verify, macro display

- Find Life Tap ranks by spell ID (FindSpellBookSlotByID) with name scan fallback
- /slt verify [adopt|reset] compares BASE table to C_Spell.GetSpellDescription
- Macro buttons with /slt cast show the current rank (C_Macro.SetMacroDisplay)
- Debug output of raw combat log values to confirm powerType position
- Options: macro display checkbox, taller standalone window
