Add ThinkNode M7 hardware model to API device resource list

[Copilot]

This updates the API hardware catalog to include Elecrow ThinkNode M7 so clients can resolve and present this board from resource.ts using current protobuf/firmware identifiers.

• Scope

  • Added a new DeviceHardware entry for THINKNODE_M7 with hwModel: 129.

• Resource mapping

  • Wired the device to firmware target thinknode_m7.
  • Set metadata to align with existing ThinkNode ESP32-S3 entries (architecture: esp32-s3, supportLevel: 1, activelySupported: true, tags: ["Elecrow"], requiresDfu: false).

• Code change (excerpt)
