Fix apt-cacher-ng: use working pattern from deb-mock workflow

- Replace complex apt-cacher-ng setup with proven working pattern
- Use direct IP address (192.168.1.101:3142) like in deb-mock workflow
- Remove separate apt-cacher-ng container setup step
- Use sources.list configuration instead of apt proxy configuration
- This matches the working pattern from apt-ostree and deb-mock workflows

The previous approach was too complex and not working. This uses
the exact same pattern that works in your other CI workflows.
