fix: Clear selected collection type when deleted from Content-Type Builder

[Copilot]

When deleting the last collection in Content-Type Builder, the deleted collection name persisted in the UI instead of showing the empty state.

Changes

• Added NGRX effect clearInvalidSelectedType$ in collection.effects.ts to clear selectedType when collection types reload and the current selection is invalid
• Fixed Angular 20 compatibility in app.config.server.ts by removing deprecated provideServerRouting

The effect reacts to loadCollectionTypesSuccess and dispatches setContentType({ selectedType: '' }) when the current selection no longer exists:

clearInvalidSelectedType$ = createEffect(() =>
  this.actions$.pipe(
    ofType(CollectionActions.loadCollectionTypesSuccess),
    withLatestFrom(this.store.pipe(select(selectSelectedType))),
    filter(
      ([action, selectedType]) =>
        selectedType !== null &&
        selectedType !== '' &&
        !action.collectionTypes.includes(selectedType)
    ),
    map(() => ContentActions.setContentType({ selectedType: '' }))
  )
);

The UI already handles empty selectedType by displaying the empty state - no component changes needed.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>Show empty state in Content-Type Builder when no Collection is selected</issue_title>
<issue_description>Currently when you delete the last collection in the Content-Type Builder the name of the last collection is shown in the main view when there is no one. This is likely an NGRX issue that needs to be fixed in the reducer.</issue_description>

<agent_instructions>Make this as simply as possible and use conventions from the project. This should be changed in CCUI.DAPPI angular project. No changes in the backend should be requiired</agent_instructions>
