feat: Add systemd service to monitor boot disk space
This commit introduces a new systemd service that runs daily to check the disk usage of the /boot partition. If utilization exceeds a set threshold, it triggers a warning email. This will ensure prompt alerts on critically low boot disk space, helping in maintaining a stable system.
