Fix the Nampower SPELL_MISS argument order

TriggerSpellMissEvent signals casterGuid, targetGuid, spellId, missInfo for
both SPELL_MISS_SELF and SPELL_MISS_OTHER. Both handlers read arg1 as the
spell ID, so every miss dispatched a GUID string where an ID was expected
and no miss ever reached the immunity recorder through the Nampower path.

Name mechanic 14 knockout to match the 1.12 DBC, and normalise CC type input
through one place so incap and incapacitate stay accepted as aliases for it.
