fix: correct telemetry type values for PVE and addon scripts

- PVE scripts (tools/pve/*): change type 'tool' -> 'pve'
- Addon scripts (tools/addon/*): fix 4 scripts that wrongly used 'tool' -> 'addon'
  (netdata, add-tailscale-lxc, add-netbird-lxc, all-templates)
- api.func: post_tool_to_api sends type='pve', default fallback 'pve'
- Aligns with PocketBase categories: lxc, vm, pve, addon
