Cluster health remediation: cleanup CronJob, disable Collabora, fix GPU probe, add NFS exports [ci skip]

- Add daily CronJob to auto-clean Failed/Evicted pods cluster-wide (infra-maintenance)
- Disable Collabora in Nextcloud (broken HPA caused scaling storm; using OnlyOffice instead)
- Increase gpu-pod-exporter liveness probe timeout from 1s to 5s
- Add osm-routing NFS exports (osrm-data, otp-data)
