fixes (12)
- Reuse valid admission webhook certificates during Helm upgrades, preventing unnecessary certificate rotation and certificate trust errors
- Fix gang scheduling for Pods that request only DRA resources, preventing pending Pods from satisfying gang readiness or bypassing gang constraints through backfill
- Avoid double rollback after pipeline failures during gang eviction simulation, preventing DRF resource-accounting panics
- Include descendant queues' scheduling-gate reservations in ancestor capacity checks, preventing gate removal from exceeding parent queue quotas
- Keep completed PodGroups in the Completed phase as finished Pods are deleted, preventing queue quota from being reserved again
- Clear stale node nominations after rollback and correct preemption eligibility when nominated nodes are schedulable or deleted
- Exclude nodes from preemption candidates when any predicate reports an unresolvable failure, preventing unnecessary victim evictions
- Stabilize PodGroup scheduling failure messages to avoid unnecessary status updates and changing event messages for unchanged failures
- Correctly finalize JobFlows whose jobs finish before the first reconciliation, avoiding flows stuck in Running and skipped job cleanup
- Return errors for unsupported output formats in vcctl JobFlow and JobTemplate describe commands instead of exiting successfully
- Filter the queue overview Running GPU panel by the selected queue
- Show all queues in the memory capacity panel instead of only the root queue
