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).
