Subject: [PATCH] coa: dynamic PopulateListFrame buttons for 21 CoA custom
 classes

Closes the deferred UI piece from 32324ff. The 11 vanilla class buttons
in Dcr_lists.xml stay hardcoded so this fork keeps working on stock
clients with no CoA extras (DC.ClassNumToUName produces 0 entries at
idx >= 22 there, builder returns early).

D:BuildPopulateExtraClassButtons(frame) walks DC.ClassNumToUName for
keys 22+, sorted, and creates one GameMenuButtonTemplate per class:
  - First extra fills row 6's empty right column (beside Hero)
  - Remaining alternate left/right, chained off Hero / Deathknight
  - Frame grows by ceil((n-1)/2) * 20 px so the existing BOTTOM-anchored
    Close button slides down with it
Idempotent via frame.coa_extras_built.

Wired from DecursivePopulateListFrame OnShow with a Dcr.BuildPopulateExtraClassButtons
nil-guard so an out-of-order load doesn't break the frame.

Bumped toc to Asc-1.1.1-coa.
