fix(tk2): honor consume_item_type (ticket/crystal/rupy/free) + correct entry ticket id

- ArenaTwoPickConfig: add TicketItemId=1, TicketCost=1, CrystalCost=150, RupyCost=150 scalars
- ArenaTwoPickService.EntryAsync: switch on eARENA_PAY (1/3/4/5); crystal/rupy go through
  ICurrencySpendService.TrySpendAsync; ticket uses item id 1 (challenge ticket, not 80001);
  free entry returns empty reward_list; invalid type throws
- Tests: fix ticket id 80001→1 in entry/e2e; add 4 new path tests; update ctor (10th arg)
  across all 4 service test files; fix e2e retire assertion (reward ticket 80001 post-state=1)
