Backend:
- Seed OCI classification from previous state so containers never
'downgrade' to LXC if config fetching intermittently fails
- Prevent type regression in recordGuestSnapshot when OCI was previously detected
- Move metrics zeroing before snapshot recording for cleaner flow
Frontend:
- Add isOCIContainer() memo that checks both type and isOci flag
- Use isOCI helper in Dashboard.tsx for AI context building
- Include oci-container type in useResources container conversion
- Preserve isOci and osTemplate fields through legacy conversion
This ensures OCI containers retain their classification even when
Proxmox API permissions or transient errors prevent config reads.
