refactor(hub): rename Device ID to Hub ID in console layer

Rename the business-layer concept from "Device ID" to "Hub ID" for
better user comprehension. The underlying network transport layer
still uses deviceId — Hub ID is passed as the deviceId value.

- Rename device.ts → hub-identity.ts, getDeviceId → getHubId
- Storage file: ~/.super-multica/device-id → ~/.super-multica/hub-id
- Hub property: deviceId → hubId
- API response field: deviceId → hubId
- Console UI label: "Device ID" → "Hub ID"
