coa.10: CoA reputation factions (data-driven) + custom-class icons + all-professions Skills

- Reputation view rebuilt data-driven from each char's scanned factions grouped
  by in-game category; CoA custom factions (and future ones) appear automatically.
  Old hardcoded tree kept only as an icon lookup.
- CoA custom-class icons (classes 12-32) render from bundled atlas
  Altoholic/images/coa-classes.blp (texcoords from coa-details) instead of the
  Warrior glue-icon fallback in ShowClassIcons.
- Skills tab shows ALL known professions (dynamic list incl Woodcutting/Woodworking),
  not 2 fixed slots; DataStore_Skills scans on PLAYER_ENTERING_WORLD/SKILL_LINES_CHANGED
  (fixes 'no profession data' that only scanned on ghost-release).

+-- WoW's _G.CLASS_ICON_TCOORDS only carries texcoords for the playable
+-- classes the *client* shipped with — on the CoA Voljin client that is
+-- the vanilla 10 + DEATHKNIGHT only. The 21 CoA custom classes
+-- (BARBARIAN, WITCHDOCTOR, CHRONOMANCER, …) have no entry, so any draw
+-- site that does `CLASS_ICON_TCOORDS[class]` falls back to a wrong or
+-- blank icon (Altoholic.lua:ShowClassIcons hit this).
+--
+-- The realm-authoritative class-icon atlas is the 512x512 (8x8 grid of
+-- 64px cells) BLP that the CoA Details! fork bundles and renders for
+-- all 32 classes. We ship a copy of that atlas as
+-- Interface\AddOns\Altoholic\images\coa-classes.blp and reproduce its
+-- per-token texcoords below (source: Details/functions/profiles.lua
+-- class_coords). Keyed by the UPPERCASE englishClass token — the same
+-- key DataStore stores (DataStore_Characters: UnitClass()'s 2nd return)
+-- and CLASS_ICON_TCOORDS uses, so it is a drop-in for both.
+--
+-- Includes the vanilla 10 + DK too, so a single lookup covers every
+-- CoA-playable class uniformly out of one texture.
