fix: install __hpc_base_packages early via dedicated task

Add a new top-level "Install base packages" task to ensure the role’s baseline
packages (defined in __hpc_base_packages) are installed consistently and
independently of optional feature blocks such as Moneo.

The task is placed immediately after repository configuration so required repos
are available before package installation, and it uses the same OSTree-safe
package backend selection pattern used elsewhere in the role.

this change only introduces a common baseline package installation step.
