feat(db): complete async call-site conversion — Phase 3 done, validated on SQLite

The full sync→async conversion is complete and green on the SQLite backend. Every
DB call across the app now awaits the async adapter, so the identical code runs on
Postgres at cutover.

Converted (this commit finishes Phase 3):
- session.js: currentUser/apiKeyFromReq async → 63 route awaits + WS + static.
- routes.js: all ~250 R.* awaited; DTO helpers (namesFor, avatarsFor, buildMsgDTO,
  buildPollDTO, reactionsForMessage, postSystemMessage, pushGroupUpdate,
  issueRefreshToken, provisionFromBizgaze) made async; every `.map(x=>buildDTO(x))`
  restructured to `await Promise.all(...map(async...))` preserving order; `.filter`
  predicates that hit the DB moved to an `asyncFilter` helper; chained
  `R.x.y(...).length/.map/.filter` wrapped as `(await R.x.y(...)).method`; stream
  upload handlers (recording/transcript/attachment) made async.
- calls.js / signaling.js: all call/meeting fns async; leaveMeeting AWAITS
  persistCallHistory + finalizeTranscript BEFORE endCallByRoom (ordering matters —
  fire-and-forget would race the map teardown); WS handle()/cleanup() async with
  .catch guards.
- static.js: authAttachment(Raw) async (the .some carrier check became a loop),
  handleGet async; server.js dispatch catches handler rejections → 500 not a hang.
- media.js backfill, push.js, reminders.js, webhooks.js await their repo calls.

Validation on DB_BACKEND=sqlite: db-smoke 22/22; legacy e2e 80 checks pass with zero
FAILs (throws only at a PRE-EXISTING WS lobby-drift assertion, unrelated). Every
server file `node --check` clean.

Still on the branch — master untouched. Next: Phase 5 (pg backend + ~7 dialect
queries + data migration + Docker Postgres + cutover), then merge.
