P2R-02 slice 5: dashboard row Run-now uses covering schedule

Replace the placeholder 'Open →' link with a per-host Run-now
decision computed server-side once per render:

* If the host has exactly one enabled schedule whose source-group
  set covers every group on the host → primary 'Run all groups'
  button (HX-POST to that schedule's /run endpoint, fires every
  backup the host knows about in one click).
* Otherwise (zero matches, multiple matches, or any ambiguity) →
  ghost 'Open →' link to /hosts/{id}/sources, where the operator
  picks per-group from the source-group rows.

dashboardPage.Hosts moves from []store.Host to []dashboardHostRow
to carry the precomputed RunAllScheduleID; host_row.html now reads
.Host.* and .RunAllScheduleID. Two extra store calls per host on
dashboard render — fine at fleet sizes we care about; if we ever
need to support thousands of hosts we'll batch these queries.
