coa.19: revert the window enlargement (restore original 832x447 frame)

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).
