Improve unattended mode detection and export MODE

Enhanced the is_unattended() function to prioritize the MODE variable for detecting unattended/non-interactive mode, with detailed handling for various modes and legacy fallbacks. Also, export MODE in build_container() to inform install scripts about the current mode. Updated APP name in forgejo-runner.sh for consistency.
