feat(billing): multi-user paywall: multi_user capability, 20-day grace, owner-only dormancy (#2099)

* feat(billing): multi-user seat gate: multi_user capability, 20-day grace, owner-only dormancy

Multiple people in one company becomes a paid capability (multi_user, the
eighth PAID key). Derived at access time from capability_grants, no status
column, no enforcement cron:

- entitled: active grant (trial/stripe/team/manual/comp), everyone works
- grace: newest grant expired < 20 days ago; countdown banner for everyone
  in companies with > 1 user; invites still allowed
- frozen: only role=owner resolves; other memberships go dormant (rows
  untouched, paying reactivates instantly); invites 403 with paid-plan upsell

Enforcement: new resolve_active_company_gated RPC (zero-arg RPC and RLS twin
untouched: they also run on self-hosts, where the gate never bites), gated
query fallback for service-role/API-key paths, setActiveCompany guard, MCP
company-access check, invite route. Middleware routes all-frozen users to a
new /paused page; the switcher greys locked companies.

Migration 20260901081417 (applied to staging): trial trigger seeds
multi_user, backfills for mid-trial companies, active Stripe subs, team
agreements, and a grandfather grant (expires now, i.e. grace = deploy + 20
days) for existing unpaid multi-member companies. Daily cron mails owners at
grace start and last day. Strings in sv+en; pg-real + unit tests included.

* fix(billing): multi-user seat gate hardening from skeptic review

- Stripe cancel now EXPIRES the multi_user stripe grant instead of deleting
  it: the 20-day grace window hangs on an expired row, so a deleted one
  froze churned payers' staff instantly with no banner and no mail. Other
  stripe grants keep the freeze-and-retain delete.
- New SECURITY DEFINER company_multi_user_state() RPC (migration
  20260901083726, applied to staging) and RPC-first getMultiUserState:
  capability_grants RLS hides team-scoped rows from non-team users, so
  user-client reads misread byra-covered companies as frozen (switch
  refusal, wrong switcher locks).
- Byra-kind teams get a standing team-scoped multi_user grant (backfill +
  teams trigger): byra client companies have no company-scoped trial by
  design, so a grantless byra team would freeze every consultant and
  client user.
- Comped/manual companies with active PAID-key grants extend to multi_user
  (a comped company must not read as paying while locking out user two).
- /api/v1 gets the same dormancy gate as MCP (frozen non-owner -> 403).
- PGRST202 on resolution fails OPEN (pre-migration DB has zero multi_user
  rows; the gated fallback would have frozen every non-owner mid-deploy).
- Grace cron: covers team-scoped lapses (byra agreement ending) and skips
  the start mail for the hand-mailed grandfather cohort.
- Tests updated/added across all touched surfaces; pg tests for the new
  RPC and byra trigger; trial-suppression pg test extended to 8 keys.

* fix(billing): decouple seat-gate env check and fail open on gate read throws

CI round 1 on #2099:
- isMultiUserEnforced no longer imports has-capability: several route test
  suites partially mock that module and the vitest mock guard threw from
  inside the v1 seat gate, turning expected 4xx responses into 500s.
  multi_user is never a connector capability, so the bypass reduces to the
  same env reads, now inlined.
- getMultiUserState wraps its resolution in a fail-open try/catch: a client
  without .rpc or a thrown network error must never lock users out.
- no-phantom-columns ceiling 391 -> 393 with reasons: the seat gate's .or()
  scope filter (server-resolved UUIDs) and the Stripe cancel expiry update's
  timestamp .or(); all columns in both strings are literals.

* fix(billing): membership-guard the multi-user entitlement RPCs (Superagent P3)

company_multi_user_ok and company_multi_user_state are SECURITY DEFINER and
were granted to authenticated with a caller-supplied company UUID: any
logged-in user could probe an arbitrary company's billing state and grace
deadline across tenants. Migration 20260901091752 (applied to staging)
requires an auth.uid() membership in the target company when a JWT is
present, keeps service-role/definer contexts unrestricted, and clamps the
grace window to [0, 20] days. pg tests: stranger gets false/NULL, member
reads normally, oversized p_grace_days cannot widen the probe.

* Multi-user grace countdown: shown to EVERYONE in a company whose
* multi_user entitlement has lapsed but is still inside its 20-day grace
* window, and only when the company actually has affected people (at least
* one non-owner member). The affected member reads their own version; the
* owner (and everyone else) reads which accounts pause and when.
*
* Server-gated: the dashboard layout renders this only in the grace state
* with a non-empty affected list, so the component itself only formats.
* Same chrome treatment as SandboxBanner: environment notice on secondary,
* never a warning fill (status colors are data, not chrome).
