feedback7: merge fb7-ui-backlog — #229 device tooltips, #238 settings button in lobby / room, #138 准备 folds the shop, #120 in-match spectator roster (cap stays 2), PR #308 capsule counts (+ the shared-field progress fix), PR #333 empty new shop slot on 调度中心 upgrade

- Conflicts: the stats entry (merged fb7-stats) and the settings button both sit in the lobby / room top bars — both kept;
  public/js/ui/settings.js (#321 diagnostics, voiceLang, SettingsButton); docs/PLAYING.md table rows resolved line by

  (resolved + ammo / wolves / neg / stand / standCut); design/client.md Screens line (#368's AI switch kept).
- Grok review: MERGE AFTER FIXES — the shared-field capsule finding fixed on the branch (1a880699).
- Golden: roster 23, bonds 2, fields 11, matches 18, diy 11 — #308 totals / snapshots and #333's shop RNG (union OK);
