Use ClassicAPI for action-bar mapping, spell IDs, and dynamic pfUI icons

GetActionInfo:
- Add ClassicAPI.GetActionInfo wrapper; rewrite GetActionButtonInfo
  (Generic.lua) to use it and resolve names via GetSpellRecField /
  GetItem / GetMacroInfo, replacing the per-slot GameTooltip scan +
  texture heuristic. Powers reactive-ability slot detection.
- Delete the dead SuperWoW-GetActionText copy of GetActionButtonInfo.

Spell IDs in the index:
- IndexSpells now uses ClassicAPI GetSpellInfo(slot, bookType), whose
  10th return is the spellID, so every Spells entry carries .id (one
  call also replaces GetSpellName + GetSpellTexture).

Dynamic pfUI action-button icons (pairs with the pfUI fork change):
- GameTooltip.SetAction hook renders spells via ClassicAPI
  SetSpellByID(spell.id) instead of SetSpell(spellSlot, bookType) +
  manual rank text. Items stay location-based (instance data).
- Drop the redundant GetActionSpellSlot -> GetSpellCooldown cooldown
  shim in the pfUI handler; pfUI now routes through the hooked
  GetActionCooldown when it defers macro scanning to us.
