- Practice finish now grants win/loss XP via IBattleXpService.GrantAsync
with BattleXpMode.Practice. Response fields (get_class_experience,
class_experience, class_level) reflect post-grant totals.
- Uses req.ClassId from wire; no BattleContext lookup needed.
- Test asserts default XpPerWin=100 crosses classexp.csv L1=50 threshold
→ Level=2 + Exp=50 carry, persists to Viewer.Classes.
- Added loss-XP test asserting default XpPerLoss=25 stays under threshold.

practice/deck_list returns the same wire shape as /deck/info (the client parses
both via DeckGroupListData), but only ever sent user decks — so a fresh account
saw no default decks and couldn't start a practice match.
Extract the /deck/info hydration into a shared IDeckListBuilder used by
/deck/info, /deck/my_list, and /practice/deck_list. Practice passes
padEmptySlots:false (deck *select*, not builder) — matches the prod practice
capture, which returns real decks unpadded plus the 8 per-class default decks
and per-class leader-skin settings. Retire the near-duplicate
PracticeDeckListResponse DTO in favor of the shared DeckListResponse.
