Two things:
1. FIX a live regression the async conversion missed: chat.js calls repos via the
lazy repos() helper (not the R. prefix), so my sweep skipped it — effectiveStatus
/ broadcastPresence read `repos().users.byId(userId)` synchronously, but that's a
Promise now, so presence broadcasts always reported status 'active' and dropped
last_seen. Now awaited (effectiveStatus/broadcastPresence async); touchSeen is a
fire-and-forget UPDATE with .catch. Audited all non-R. repo calls — only chat.js
was affected (media.js backfill was already awaited).
2. Swappable pub/sub for multi-instance real-time fan-out (the actual blocker to
running >1 instance — not the DB). server/pubsub.js picks a backend by
PUBSUB_BACKEND (default 'memory'). Local socket delivery is UNCHANGED; publish is
additive — memory = no-op (zero hot-path cost, identical single-instance
behaviour), redis = fan-out to other instances with a self-echo guard. chat.js
pushToUser/broadcastPresence now also publish; each instance subscribes to deliver
remote events to its local sockets. Interface is tiny so Redis is one swappable
file (Postgres LISTEN/NOTIFY or NATS could drop in the same way — never hardwired,
as requested). Dormant redis service added to compose behind the 'scale' profile;
redis dep added; PUBSUB_BACKEND/REDIS_URL documented.
Validated: smoke 22/22 (memory), e2e chat delivery green. NOTE: full multi-instance
also needs distributed presence (isOnline is per-process) + meeting-signaling
sharing — chat/presence fan out via this layer; those are follow-ups.

Adds a dedicated Postgres 16 service (container bizgaze-postgres, own named volume
bizgaze_pg_data, healthcheck) on the shared NPM network. The app depends_on it
healthy. Inert until DB_BACKEND=pg is set in .env — default stays SQLite, so this
deploy changes nothing functionally; it just makes the engine available. Documented
POSTGRES_PASSWORD / DATABASE_URL / DB_BACKEND in .env.example.

Adds the server side of scaling meetings past the ~5-peer mesh:
- config.js: LIVEKIT_URL/API_KEY/API_SECRET + LIVEKIT_ENABLED flag. All optional;
when unset the app keeps the built-in P2P mesh (fully additive, like push).
- routes.js: GET /api/meetings/config (tells the client sfu on/off + wss url) and
POST /api/meetings/token (mints a per-user, per-room LiveKit join token — hand-rolled
HS256 JWT like the FCM/APNs tokens, no new dependency; secret stays server-side).
- docker-compose.yml: optional livekit service (single-node, no Redis), keys injected
via LIVEKIT_KEYS from the same .env; media over published UDP 50000-50100 + TCP 7881,
signaling proxied by NPM.
- livekit.yaml + .env.example documented.
Client (mesh->LiveKit media swap, behind the flag) lands in phase 2.

User-facing
- New post-login home (/home): chat rail + Share/Connect (embedded) + Meeting; login lives here when logged out
- Landing: "Log in with BizGaze" + no-login screen share
- Console replaced by a role-scoped Dashboard (/dashboard): admins see all team sessions, others see only their own; stats + CSV/PDF export
- Recordings saved as MP4 (H.264/AAC) with WebM fallback; old .webm still downloadable
- Fix: duplicate "Sign in" on the login card
Auth / integration
- BizGaze as identity provider: /api/login validates against BIZGAZE_LOGIN_URL (env-gated) and provisions a local user
- Phase 2 start: /api/v1 alias for all /api routes; Authorization: Bearer accepted across HTTP + WS; login returns a token (for native desktop/mobile clients)
Backend refactor (Phase 1, behavior-preserving)
- Split server.js into config/lib/session/presence/routes/static/signaling + repos (data-access) + bizgaze (service)
- All SQL behind repos.js, tenant-scoped (tenantId == team_id for now)
- e2e updated to current flow (21/21 pass before and after)
