## Summary by CodeRabbit

* **New Features**
* Current user profile now exposes access tokens, revealed tokens, and
detailed calendar accounts/subscriptions.
* Workspace now exposes permissions, calendars, calendar events, and a
workspace-scoped blob upload part URL.
  * New document-update mutation for applying doc updates.

* **API Changes**
  * validateAppConfig is now a query (mutation deprecated).
* Several legacy top-level calendar/blob endpoints deprecated in favor
of user/workspace fields.

* **Refactor**
* Calendar, blob-upload and access-token surfaces reorganized to use
user/workspace-centric fields.
