feat(federation): queue S2S presence_update on auth/disconnect/status/activity changes

New FederationPresenceUpdatePayload + queuePresenceRelay() helper. Five WS sites now project the native user's status (and optional activities) to all active peers via the outbox: WS auth-success, finalizeDisconnect, manual presence_update, activity_update, showActivity-toggle clear. Outbox-only (no mutation-log entry) — presence is ephemeral; the upcoming peer-activation hook re-emits a fresh snapshot so peers recovering from unreachable converge without history replay. No-op for replicated users.
