Hardware IDs display numeric values for IMU types absent from the local enums. Read names from ArduPilot's generated devid.json so new catalog entries can be recognized without adding C# enum members.

Related to #3778. Following the feedback on this PR, the catalog is downloaded and cached locally; it is no longer embedded or shipped with the application.

• Load the local cache into a category/type lookup used by both device string output and the Hardware IDs page.
• Check for updates in the background at startup, using the existing download helper and data directory. The seven-day cache lifetime follows the existing log/parameter metadata convention.
• Validate downloads before replacing the cached file. Failed updates retain the previous valid cache; unavailable or unknown entries fall back to the existing enum/numeric display.
• Preserve the existing parameter classification, Device ID decoding and Hardware IDs DroneCAN SENSOR_ID# handling.

Validation: Windows Release build and MSI packaging succeeded. Administrative MSI extraction and hashes of the packaged EXE/DLL files were verified on the Windows runner. The downloaded MSI SHA-256 was also checked locally. Physical flight-controller validation is still pending.

Kept as a draft for discussion of the download/cache approach.

it should be downloaded and cached, not embedded
