fix(api): make memCache a required field in SandboxMetric schemas

All other metric fields (memUsed, memTotal, diskUsed, etc.) are required in
the OpenAPI specs. Leaving memCache optional caused oapi-codegen to generate
it as a pointer (*int64) with omitempty, which is inconsistent with the rest
of the struct and would make it the only metric that could be absent from API
responses.
