The coa.12 enlargement couldn't extend WoW's fixed AuctionFrame art cleanly -> fragmented
background + broken scrollbar. Reverted to the original clean frame (14 rows, intact art,
working scrollbar). All crash fixes, Skills professions cap, login-scan, class icons, and
the char-view profession wrap are preserved (they live in different lines/files).
- Hardening sweep across DataStore_* (softened crash-asserts in Talents/Containers/Quests
to graceful nil) + Altoholic frames (guarded remaining getter results).
- DataStore_Characters: scan on login (was ghost-gated -> name/level/class never populated;
the core 'no character data' cause).
- Skills tab: cap inline professions at 6 (+N) so the strip stops overflowing into Cooking.
