## Summary
Adds the ability to backfill application installations across all
existing workspaces. This allows admins to retroactively install a
pre-registered application on every active and suspended workspace
through a background job, making the feature idempotent and
non-blocking.

## Key Changes

- **Backend Service**: Added `backfillApplicationOnAllWorkspaces()`
method to `PreInstalledAppsService` that:
  - Validates the application registration exists
  - Iterates through all workspaces using `WorkspaceIteratorService`
  - Installs the app on each workspace
  - Swallows `APP_ALREADY_INSTALLED` errors for idempotency
  - Logs success/failure counts

- **Background Job**: Created `BackfillApplicationInstallationJob` to
process backfill requests asynchronously via the message queue

- **GraphQL Mutation**: Added `backfillApplicationInstallation` mutation
to `AdminPanelResolver` that:
  - Validates the application registration exists
  - Enqueues the background job
  - Returns immediately without blocking the request

- **UI Components**: Enhanced
`SettingsAdminApplicationRegistrationGeneralToggles` with:
- New "Pre-install on new workspaces" toggle for the `isPreInstalled`
flag
  - "Backfill on all workspaces" button with confirmation modal
  - Loading state and success/error snack bar feedback

- **Data Model**: Added `isPreInstalled` field to
`UpdateApplicationRegistrationPayload` input type

- **Tests**: Added comprehensive unit tests for
`PreInstalledAppsService.backfillApplicationOnAllWorkspaces()` covering:
  - Missing registration validation
  - Successful multi-workspace installation
  - Idempotent handling of already-installed errors
  - Proper error propagation for unexpected failures

## Implementation Details

The backfill operation is designed to be:
- **Idempotent**: Already-installed apps are skipped without error
- **Non-blocking**: Runs as a background job via message queue
- **Resilient**: Per-workspace failures don't block other installations
- **Observable**: Logs aggregated success/failure counts for monitoring
