* Switch container exec from bash to sh in fix_gpu_gids
Replaces bash with sh for container execution in fix_gpu_gids and updates device matching logic to use a POSIX-compliant case statement. This improves compatibility with containers that may not have bash installed.
* fix(apt): auto-recover from interrupted dpkg operations
When a previous installation is interrupted (e.g., by script error or
user cancellation), dpkg can be left in an inconsistent state requiring
'dpkg --configure -a' to fix.
This change:
- Adds dpkg --configure -a check to ensure_apt_working()
- Adds dpkg --configure -a to retry logic in install_packages_with_retry()
- Adds dpkg --configure -a to retry logic in upgrade_packages_with_retry()
Fixes: Omada Controller update failing after interrupted installation
