Get-PveCloudInitConfig and Get-PveTemplate each built their own PveHttpClient
inline. They now go through CloudInitService and TemplateService, which is
offline-testable per ADR 0021.
Get-PveCloudInitConfig's shipped output is the full PveVmConfig (per its own
synopsis), not the CI-key-filtered PveCloudInitConfig that
CloudInitService.GetCloudInitConfig already returns for a different purpose.
CloudInitService gains GetFullVmConfig, a thin delegation to the existing
VmService.GetVmConfig (already used by Get-PveVmConfig) rather than a
parallel HTTP implementation.
Get-PveTemplate's TemplateService.GetTemplates now forwards VmService.GetVms's
onNodeSkipped callback, matching Get-PveVm/Get-PveContainer, so an unreachable
node during the all-nodes listing produces a warning instead of a silently
short result. Two review-found regressions were fixed before commit: an empty
-Node value used to mean "query all nodes" and now does again (it had
started reaching the API literally as nodes//qemu), and the per-node warning
above.
