OnlineSyncService is registered once at startup; toggling the feature off
in Settings persisted the flag but never stopped the running loop, so it
kept polling and failing OIDC discovery every cycle. Guard TickAsync on
the shared config's Enabled flag so disabling takes effect live.
Plumb a per-resource owner (Zitadel sub) through the sync contract without
enforcing isolation client-side — the server stays the authority.
- Dtos: add optional ownerId to RemoteList/RemoteTask/MirrorTask
- JwtClaims: decode the sub claim from the access token (never throws)
- OnlineSyncService: stamp ownerId on pushed lists + mirror; defensively skip
pulled tasks owned by a different user (unowned tasks still sync, so
single-user behavior is unchanged)
- docs: contract documents ownerId + multi-user readiness

Optional, opt-in (online_inbox.enabled, default false → zero network).
Worker-side reconcile loop: pull web-created tasks down as Idle, push the
list catalog and the Idle backlog mirror up. Auth behind IOnlineAuthProvider
(StaticTokenAuthProvider default; ZitadelAuthProvider stubbed for Phase 2).
DPAPI refresh-token store. 35 tests, no real network/Zitadel/Claude.
