Backend changes:

1. bambu_mqtt.py: Added hms_errors to the completion callback data, which includes the HMS error codes when a print fails
  2. archive.py: Updated update_archive_status() to accept an optional failure_reason parameter
  3. main.py: Added auto-detection of failure reasons:
    - status == "aborted" → failure_reason = "User cancelled"
    - status == "failed" with HMS errors → maps module codes to reasons:
        - Module 0x07 (Filament) → "Filament runout"
      - Module 0x0C (Motion Controller) → "Layer shift"
      - Module 0x05 (Nozzle) → "Clogged nozzle"

  Frontend changes:

  1. ArchivesPage.tsx:
    - Badge now shows "cancelled" for aborted prints, "failed" for failed prints
    - "Failed Prints" collection and "Hide Failed" filter now include both failed and aborted statuses
  2. EditArchiveModal.tsx: Failure reason field now shows for both failed and aborted prints

  New tests added:
  - test_hms_errors_included_in_failed_completion_callback
  - test_aborted_status_when_cancelled

  The HMS error module mapping is basic and can be expanded as you observe more failure types. The actual Bambu HMS error codes are documented in their wiki - we can add
  more mappings as needed.
