These addon Kustomizations were using wait=true, which made Flux treat transient
HelmRepository fetch timeouts as addon failures even when the HelmRelease and
runtime workloads were healthy. Switch the affected Kustomizations to explicit
HelmRelease healthChecks so readiness reflects the actual deployed platform
state instead of repository fetch flakiness.
Replace Hetzner infrastructure and cloud-provider assumptions with Proxmox
VM clones, kube-vip API HA, and NFS-backed storage. Update bootstrap,
Flux addons, CI workflows, and docs to target the new private Proxmox
baseline while preserving the existing Tailscale, Doppler, Flux, Rancher,
and B2 backup flows.
