## Summary
Add a new "Installed workspaces" section to the application registration
settings page that displays all workspaces that have installed a given
application, with pagination support.
## Key Changes
- **Backend Service**: Added `getInstalledWorkspaces()` method to
`ApplicationRegistrationService` that queries installed applications
across workspaces with pagination support
- **Backend DTO**: Created
`ApplicationRegistrationInstalledWorkspacesDTO` and
`InstalledWorkspaceDTO` to structure the response with workspace details
(id, displayName, logo, version), total count, and hasMore flag
- **GraphQL Resolver**: Added
`findApplicationRegistrationInstalledWorkspaces` query resolver with
pagination (page parameter, default page size of 10) and proper
authorization guards
- **Frontend Component**: Created
`SettingsApplicationRegistrationInstalledWorkspaces` component that:
- Displays installed workspaces in a table with workspace logo, name,
and version
- Shows initial 3 workspaces with "Show all" button to expand
- Implements pagination with "Show more" button to load additional pages
- Handles empty state (returns null if no workspaces installed)
- **GraphQL Query**: Added
`FindApplicationRegistrationInstalledWorkspaces` query document for
frontend data fetching
- **Integration**: Integrated the new component into
`SettingsApplicationRegistrationGeneralTab`
## Implementation Details
- Pagination uses offset-based approach with configurable page size (10
workspaces per page)
- Query results are ordered by workspace displayName and id for
consistent ordering
- Soft-deleted applications and workspaces are excluded from the list
and counts
- Apollo Client's `fetchMore` with `updateQuery` merges paginated
results into the cache
- Component respects existing authorization (API_KEYS_AND_WEBHOOKS
permission required)
- Uses existing UI components (Table, Card, Avatar, Button) from
twenty-ui library
- Supports internationalization with Lingui
## Screenshots
The new "Installed workspaces" section on the app registration General
tab (admin app detail page), captured against a local instance with a
demo app installed in 14 workspaces. The three PNGs are committed under
`.github/assets/screenshots/installed-workspaces/` and render inline in
the **Files changed** tab of this PR:
- `1-first-3-show-all.png` — Collapsed: the first 3 installed workspaces
(avatar + name + installed version) with a "Show all" button.
- `2-expanded-show-more.png` — "Show all": the first page of 10
workspaces, with a "Show more" button (more remain).
- `3-all-paginated.png` — "Show more": all 14 workspaces loaded, button
gone.
