fix: harden token renewal and soften refresh token revocation (#19175)

## Summary
- **Apollo factory** (`apollo.factory.ts`): Bail early with `EMPTY` when
no token pair exists so no request is forwarded without credentials.
Propagate renewal success/failure as a boolean so failed renewals stop
the operation chain instead of forwarding with stale tokens.
- **Refresh token service** (`refresh-token.service.ts`): When a revoked
refresh token is reused past the grace period, reject only that token
instead of mass-revoking all user tokens. The most common cause is a
lost renewal response (e.g. navigation during refresh), not actual token
theft. This eliminates the "Suspicious activity detected" errors users
were seeing. Also switches to `findOneBy` since the `appTokens` relation
is no longer needed.

## Test plan
- [x] `refresh-token.service.spec.ts` — all 7 tests pass
- [ ] Verify login flow: sign in from `app.localhost`, get redirected to
workspace subdomain without "Suspicious activity" errors
- [ ] Verify token renewal: let access token expire, confirm silent
renewal works and operations resume
- [ ] Verify concurrent tabs: open multiple tabs, let tokens expire,
confirm no mass revocation cascade
