fix: resolve 21 pre-existing schema field drift failures

- Fix InfoOs: remove codepage (not in schema, codename already queried)
- Fix InfoVersions: use core { unraid api kernel } and packages { ... }
  subtype structure instead of flat field list; remove non-existent fields
- Fix Info: remove apps field from overview query (not in Info type)
- Fix Connect query: replace missing status/sandbox/flashGuid with
  dynamicRemoteAccess { enabledType runningType error }
- Fix CpuUtilization: replace used with percentTotal
- Fix Service: remove state field, add online and version
- Fix Server: replace ip/port with wanip/lanip/localurl/remoteurl
- Fix Flash: remove size field (not in schema)
- Fix UPSDevice: replace flat runtime/charge/load/voltage/frequency/temperature
  with nested battery { chargeLevel estimatedRuntime health } and
  power { loadPercentage inputVoltage outputVoltage } sub-types
- Fix ups_device variable type: PrefixedID! -> String! (schema uses String!)
- Fix UPSConfiguration: replace enabled/mode/cable/driver/port with
  service/upsCable/upsType/device/batteryLevel/minutes/timeout/killUps/upsName
- Fix storage unassigned query: unassignedDevices not in schema, use disks
- Fix docker logs: add subfield selection for DockerContainerLogs type
- Fix docker networks/network_details: move from root dockerNetworks/dockerNetwork
  to docker { networks { ... } }; filter by ID client-side for network_details
- Fix docker port_conflicts: replace containerName/port/conflictsWith with
  containerPorts { privatePort type containers { id name } } and lanPorts
- Fix docker check_updates: replace id/updateAvailable/currentVersion/latestVersion
  with name/updateStatus per ExplicitStatusItem schema type
- Fix keys queries: add subfield selection for permissions { resource actions },
  remove lastUsed (not on ApiKey type)
- Fix health.py comprehensive check: use versions { core { unraid } }
- Update docker mutations coverage assertion to include 11 organizer mutations
- Update test_networks mock to match new docker { networks } response shape
- Update health.py runtime accessor to follow new versions.core.unraid path
