<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **New Features**
* MCP Server integration available in cloud workspaces with a dedicated
settings panel.
* Manage personal access tokens: generate/revoke tokens and view
revealed token.
  * One-click copy of a prefilled server configuration JSON.
  * New query to fetch revealed access tokens.

* **Improvements**
  * Integration list adapts to workspace type (cloud vs. local).
* More reliable token refresh with clearer loading, error and
revalidation states.

* **Localization**
* Added “Copied to clipboard” message and MCP Server name/description
translations.

* **Chores**
  * Updated icon dependency across many packages.
