• Fix Assisted Combat localization and improve error message
  Use Blizzard's global string ASSISTED_COMBAT_ROTATION for proper localization
  (shows "Einzeltasten-Assistent" in German clients). Add clearer error message
  explaining AC can only be bound to action bar slots.

• Fix critical API bug: Check spell_id before calling IsSpellKnown
  The All-in-One version was calling C_SpellBook.IsSpellKnown() before
  checking if spell_id exists, causing a Lua error on Retail when nil
  spell_id values were encountered (e.g., FLYOUT spells).
  Fixed by wrapping API calls in 'if spell_id then' block, matching the
  pattern from the working retail branch.
  Error fixed:
  'bad argument #1 to IsSpellKnown (Usage: local isKnown =
  C_SpellBook.IsSpellKnown(spellID [, spellBank]))'
