fix(k8s): Recreate singletons and trim requests for scheduler headroom
RollingUpdate with default maxSurge needs a spare pod the single node does not have (99% CPU requested), so multi-workload restarts end Pending and verify times out. Recreate on all replicas:1 Deployments (immich-server and bentopdf keep RollingUpdate at replicas 2). Also trims CPU/memory requests toward measured use (adguard, authentik, gitea, netbox, uptime-kuma, netbird-server) and gives traefik requests/limits so it is no longer BestEffort.
