Record planned delete counts, max-delete settings, base protection, and
ignored incomplete snapshots in retention apply results.
Surface those details on run detail pages so scheduled and manual prune
outcomes are understandable without reading the raw JSON payload.
Update the scheduler to reflect the actual scheduled BackupRun status after
a run completes, so prune warnings are shown as schedule warnings instead
of being reported as successful schedule executions.
Make manual retention application more explicit by requiring operators to
confirm both the host name and the current number of planned deletions.
This reduces the risk of applying a stale or misunderstood retention plan
when the delete set changes between review and confirmation.
Show host-level retention warnings on run detail pages so successful or
warning runs still expose scheduled prune limit issues and incomplete
snapshots that need operator attention.
Show keep/delete reasons in the retention plan, surface scheduled prune
limit warnings, and explain base snapshot protection before retention is
applied.
Also surface incomplete snapshots from the retention views without deleting
them automatically, so interrupted backups are visible on the dashboard,
host detail, and retention plan.
