coa: register dispel spells for 21 CoA custom classes

Three gaps closed for CoA custom-class players:

1. DCR_init.lua C_Player:IsCustomClass() branches were stubs printing
   "CoA is not currently supported". Filled both branches (SpellsToUse +
   Spells dictionary) with 11 dispel spell IDs covering 10 CoA classes
   (Chronomancer, Cultist, Templar, Venomancer, Pyromancer, Ranger,
   Bloodmage, Runemaster, Starcaller, Witch Hunter). The other 11 CoA
   classes have no dedicated player-cast dispel in coa-db.

2. Dcr_Raid.lua ClassNumTo{LName,UName} were hardcoded to indices
   11..21 (vanilla 10 + HERO). Append every additional CLASS_SORT_ORDER
   token starting at 22 — append-only so existing DecursiveDB skip /
   priority numeric keys stay valid. CoA-class units in raids now get
   priority/skip lookups instead of silent nil-guarded no-ops.

3. Bumped toc Version to Asc-1.1.0-coa.

Spell IDs sourced from coa-db (mind_of_ascension_talent + class_spell)
filtered to effect_id=38 (DISPEL) with misc_value in {1,2,3,4} (Magic,
Curse, Disease, Poison).

PopulateListFrame XML buttons (Dcr_lists.xml) for the 21 CoA classes
deferred — needs UI rework (frame is already near-full at 11 buttons).
Skip/priority lists still work without these populate-by-class
shortcuts.
