813c5c0f29 monitoring: separate node-exporter-only external targets
Some checks failed
Run nix flake check / flake-check (push) Failing after 3m7s
Details 
Add nodeExporterOnly list to external-targets.nix for hosts that
have node-exporter but not systemd-exporter (e.g. pve1). This
prevents a down target in the systemd-exporter scrape job.

dd1b64de27 monitoring: auto-generate Prometheus scrape targets from host configs
Some checks failed
Run nix flake check / flake-check (pull_request) Successful in 2m49s
Details
Run nix flake check / flake-check (push) Has been cancelled
Details 
Add homelab.monitoring NixOS options (enable, scrapeTargets) following
the same pattern as homelab.dns. Prometheus scrape configs are now
auto-generated from flake host configurations and external targets,
replacing hardcoded target lists.

Also cleans up alert rules: snake_case naming, fix zigbee2mqtt typo,
remove duplicate pushgateway alert, add for clauses to monitoring_rules,
remove hardcoded WireGuard public key, and add new alerts for
certificates, proxmox, caddy, smartctl temperature, filesystem
prediction, systemd state, file descriptors, and host reboots.

Fixes grafana scrape target port from 3100 to 3000.
