feat(online-inbox): carry ownerId on sync to prepare for multi-user

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

**Multi-user readiness (`ownerId`).** Each resource is owned by a Zitadel subject (`sub`).
`RemoteList`, `RemoteTask`, and `MirrorTask` carry an optional `ownerId` field. The desktop
stamps its own `sub` (decoded from the access token) onto everything it pushes, and
defensively ignores any pulled task whose `ownerId` is set to a *different* user; an absent
`ownerId` is treated as unowned/legacy and still syncs. This keeps the contract ready for
multiple users **without enforcing isolation client-side** — the server remains the
authority that scopes every request by the token's `sub`. When the server goes multi-user it
should partition all rows by owner and ignore (or validate) the client-supplied `ownerId`.

`ownerId` (optional, see §1) is the Zitadel `sub` of the owner. The desktop sends it on push
and ignores pulled tasks owned by a different user; the server should derive/validate it from
the token rather than trust the client value.
