feat: improve critical reads, device list and modelPaths bug fix

- main_state_machine.ts: add to CriticalReadsState GPV:
  ProvisioningCode (confirm CPE persisted value), UpTime (detect reboots),
  ManagementServer.URL (verify ACS URL), ConnectionRequestUsername/Password
  (ensure wake credentials are always available)
- Home.vue: add Last Seen column (device.updatedAt)
- pages_controller.ts: fix modelPaths bug — was never passed to DeviceDetail,
  now auto-detected from dataModel and passed as predefined TR-181/TR-098 paths
