feedback7 R22-LOADOUT: the browser stores, syncs and shows each operator's 潜能 / 练度 (cards at the player's settings); golden: unchanged

- ui/loadoutModel.js: `ops` beside the entries (sp.pref.loadout { v, entries, ops }; an older stored loadout has none =
  潜能 6, 精英2 Lv.60): parseStoredOps, opsOf / setOps / resetOps (defaults never stored), sanitizeOps (only what the
  server keeps: the roster and the 自选 owned pool); 导出 carries `ops`, 导入 replaces the settings when the payload has
  them (an older export leaves them alone; settings alone import); the 已调整 count and 仅看已调整 count them.
- ui/loadoutSync.js: the store's `ops` (setOpsMap persists both); the loadout sync watches entries and ops and sends
  room.loadout { entries, ops } (the ops sanitised against chess.json + backups.json; nothing set: no download);
  openLoadout loads effects.json (the 练度 multipliers).
- Cards: gameLogic chessLoadout(chess, loadout, getChess, { ops | cultivation, effects }) composes the record at the
  operator's potential and multiplies its stats by the 练度 tier (the player's m.private.ops — shop / hand / board cards
  and the detail panel; a teammate's unit its UnitInfo potential / cultivate: unitCultivation; a teammate's bond-popup
  card the defaults, never the viewer's settings; a stand-in neither); a 自选 card is composed at its pick's potential
  (ownDiyPick from m.private.ops, unitPick from UnitInfo).
- Tests: test/ui/potential-ui.test.js (new, 7): storage, helpers, 导出 / 导入, the 已调整 count, the sync (sanitised ops,
  settings-only edits, no download when none), the cards (刺玫 413 / 17 at 潜能1, ×1.05 at 精英1, a teammate's unit, a
  stand-in), 自选 cards at 潜能1 (凯尔希 392 / 20) and the 练度 on top; test/ui/loadout.test.js expects the envelope's
  `ops` and room.loadout's `ops: {}`.
