🚀 feat(reset-password): Enhance CasaOS password reset script (#9)

This commit introduces several improvements to the CasaOS password reset script:

- Adds functions to print headers, check service status, and backup the user database.
- Checks if the script is run with sudo privileges.
- Displays a welcome message with links and information about supporting the project.
- Checks if the CasaOS service is active before proceeding.
- Prompts the user for confirmation before resetting the password.
- Backs up the user database before removing the original file.
- Restarts the CasaOS user service to reflect the changes.
- Provides clear success and error messages to the user.

These changes aim to make the password reset process more robust, user-friendly, and informative.
