coa.23: correct CoA class names (PROPHET->Venomancer etc.) + fix Skills rank/max

- CoA renamed classes but UnitClass returns old tokens; added a token->name map
  (CoAClassColors.lua, from coa-omen) applied in the Skills header + the shared
  AddCharacterTooltipHeader/SetCharacterRowNameLevel helpers (fixes class names everywhere).
- Skills vertical list now shows rank/max (precompute carries maxRank; was showing /0).
