## Summary by CodeRabbit

- **New Features**
  - Embedding settings UI now displays a tooltip indicating that only workspace owners can enable Workspace Embedding.
  - Embedding settings are modularized for local and cloud workspaces, with clear separation and appropriate enablement controls.
  - Attachments in embedding settings cannot be deleted when the settings are disabled.

- **Accessibility**
  - Settings wrapper now includes an aria-disabled attribute for improved assistive technology support.

- **Localization**
  - Added a new tooltip message: "Only the workspace owner can enable Workspace Embedding."

- **Tests**
  - Added end-to-end tests for local workspace UI and disabled state when not the workspace owner.

- **UI Improvements**
  - Updated settings panel to better reflect disabled states with tooltips and conditional controls.
  - Improved synchronization when opening the embedding settings panel for a smoother user experience.
