(docs) Add targeted restore examples

Browse Source 
Extend the restore guidance with directory and single-file dry-run
examples so operators can restore a focused path without copying an
entire snapshot.

Render the examples on snapshot detail pages using the selected
snapshot's data path and the host-specific staging destination.
