ci: failover round — aggregate follows the selector, tighter shared-VM bounds

Browse Source 
- all-checks-passed now resolves its pool through the same
  DSH_CI_FAILOVER expression as the worker jobs it aggregates.
  Pinned to the hosted pool it would leave the branch-protection
  verdict queued on the failed pool after every failover job passed —
  observed live during the 2026-07-27 outage as a required check
  looping against dead capacity.
- Coverage worker bound under failover drops 12 → 8 and snapshot
  concurrency 16 → 12: the pool now runs six always-on instances (the
  spare tier was retired), so worst case is 6 × 8 = 48 coverage
  workers on the shared 64-core VM.
