Add CoAClassColors.lua + bump to 5.22.0

WeakAuras reads class colours inline at two call sites with the
whole-table-pick pattern — no per-key fallback:

    WeakAuras/Types.lua:15
      local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[classFilename]
    WeakAuras/AuraEnvironment.lua:108
      local classData = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
      local coloredName = ("|c%s%s|r"):format(classData.colorStr, name)

When !ClassColors is loaded it injects a vanilla-10-only
CUSTOM_CLASS_COLORS, so the 22 CoA tokens silently miss. Types.lua
returns the white fallback; AuraEnvironment.lua:109 *hard-crashes* on
classData.colorStr.

New file mirrors any RAID_CLASS_COLORS entry that CUSTOM_CLASS_COLORS
is missing, when !ClassColors is loaded. Idempotent — only fills nil
keys, so user customisations win. Loaded after Compatibility.lua and
ahead of every Types/AuraEnvironment call site. !ClassColors added to
OptionalDeps so it loads first when installed.

Same pattern as coa-omen, coa-kui-nameplates, and
coa-shadowedunitframes.

+-- Forwards the live client's RAID_CLASS_COLORS palette into

+--
+-- Background
+-- ----------
+-- The CoA Voljin client (and the Ascension classic+ client) ship
+-- Interface/SharedXML/SharedConstants.lua with all 32 class
+-- file_strings populated in _G.RAID_CLASS_COLORS — 10 vanilla + HERO +
+-- 21 CoA customs (BARBARIAN, WITCHDOCTOR, DEMONHUNTER, FLESHWARDEN,
+-- MONK = Templar, PROPHET = Venomancer, …).
+--
+-- WeakAuras reads the colour table inline at two call sites with the
+-- whole-table-pick pattern — no per-key fallback:
+--
+--   WeakAuras/Types.lua:15 (WA_GetClassColor)
+--     local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[classFilename]

+-- When !ClassColors is loaded it injects a separate
+-- _G.CUSTOM_CLASS_COLORS populated from its own (vanilla-10-only)

+-- Types.lua:15 then returns "ffffffff" (white instead of the class
+-- colour); AuraEnvironment.lua:109 *hard-crashes* on
+-- `classData.colorStr` when classData is nil.
+--
+-- Strategy
+-- --------
+-- If CUSTOM_CLASS_COLORS exists at file-load time (i.e. !ClassColors
+-- already loaded — WeakAuras.toc declares it as an OptionalDep, so it
+-- loads first when installed), copy any RAID_CLASS_COLORS entry that
+-- CUSTOM_CLASS_COLORS is missing. Never overwrite — !ClassColors user
+-- preferences and any other addon's earlier write win.
+--
+-- We deliberately don't touch RAID_CLASS_COLORS itself: the client
+-- already populates it, and any value we'd choose here would be a
+-- guess relative to the realm-authoritative palette in
+-- SharedConstants.lua.
+--
+-- Source of truth: _G.RAID_CLASS_COLORS at FrameXML load time
+-- (Voljin/PTR realm: patch-B.MPQ → SharedXML/SharedConstants.lua).
