Fix phase1 worker count to include workers with active metrics but no leases - #1812

… leases Previously, computeSupportCodeDistribution only iterated over unexpiredLeaseOwners, causing workers that emit fleetSupportCode=SINGLE_TABLE_MIGRATION but don't hold any leases (e.g., newly started workers) to be invisible to the phase1 worker count and minSupportCode. Fix: Pass the union of unexpiredLeaseOwners + allActiveWorkersWithMetrics to computeSupportCodeDistribution. This ensures: - Workers with active metrics but no leases are included (alive) - Workers with unexpired leases but expired metrics are included (code 0) - Workers with both expired leases AND expired metrics are excluded (dead)
