Geo: Fix inaccurate "Synchronization disabled" progress bars

What does this MR do?

Uploads and Job artifacts, like many other replicable models, should never say "Synchronization disabled".

Even if there are no locally stored records to sync, it's not correct to say "Synchronization disabled". What will happen in that case is the bars will say "Nothing to sync".

(In fact, only Container Repository can legitimately say that.)

Introduced in 12.10 !28478 (merged). We need some backports.

Closes #221069 (closed)
