feat: update Docker configuration and PHP include paths

- Updated the `docker-compose.yml` to modify the app service configuration for compatibility with Laravel Octane.
- Added a backup of the original `docker-compose.yml` as `docker-compose.yml.bak`.
- Introduced a new `frankenphp-worker.php` for handling requests in the Octane environment.
- Updated PHP include paths in `.idea/php.xml` to reflect changes in dependencies.
- Modified `Dockerfile` to use `dunglas/frankenphp` as the base image and simplified the installation of PHP extensions.
- Updated `composer.json` to include Laravel Octane as a dependency.
- Revised `composer.lock` to reflect the updated dependencies and their respective versions.
