refactor(Makefile): remove App Engine configs and scripts, migrate launchpad to Cloud Run

This commit removes legacy App Engine deployment artifacts and updates the Makefile to reflect the successful migration of the `internal-launchpad` service to Cloud Run.

The following changes were made:

- Deleted obsolete permission scripts:
 - `fix-appengine-permissions-complete.sh`
 - `fix-project-level-permissions.sh`
 - `create-missing-repository.sh`
- Removed the `firebase/internal-launchpad/app.yaml` file.
- Updated `firebase.json` to remove the `launchpad` hosting configuration.

These changes streamline the repository, reduce developer confusion, and prevent the accidental use of outdated deployment logic.
