When a CNPG instance is shut down (e.g. during hibernation), the last
WAL segments might remain on local storage and not be archived to
the object store. This is because ArchiveAllReadyWALs() was only
triggered during switchover/demotion.

This commit ensures that ArchiveAllReadyWALs() is also called after
a successful smart/fast shutdown in the lifecycle loop, preventing
data loss of the final WAL segments.
