feedback1 WB: bounty-half evidence stated as a trend with its counter-evidence; queued free offers counted on the pill and header

- tools/build-data.mjs bountyDraftHalf: exact faction-series counts (12 of 18 two-battle cards bring first-half
  enemies, 5 outside the wave tables, enemyeffect_12_4 a second-half attachment), base-HP gradient, the user's
  two-battle recall; counter-evidence (假想敌 named enemyInitial_*, the unread NGA R3 guide); the split marked
  [ASSUMED] with its flip; data unchanged
- server/match/choices.js, docs/META.md, docs/DATA.md: the split marked [ASSUMED]
- m.private shop.rewardOffer.queued: offers waiting behind the shown one; the header says 之后还有 N 项 and the
  reminder pill +N (a 定向投放 behind a promotion reward put off)
- tests: corrected headers, the stale bountyTiers fixture dropped, queued checks (unit + opt-in e2e on desktop
  and 756x366)
