feat(v5): add WireGuard and coold/corrosion config to clusters/servers

Add WireGuard networking fields (interface, management pool, listen port),
container network pool, coold/corrosion versioning, and builder CPU quota
to clusters and servers via new migrations and model fillables.

Expose full cluster and server CRUD on the Clusters page with private key
selection, pending state tracking, and new form primitives (Field, Input,
Textarea). Add server status check fields and a lima test VM config for
development.
