Update scripts for Debian 13 and improve update messages

Bump default OS version from Debian 12 to 13 across all container scripts. Standardize update messages to use explicit service names and success confirmations. Refactor update functions for consistency, improve error handling, and update package management commands to use 'apt' instead of 'apt-get'.
