Support compact single-channel Viofo filenames

[nittanygeek]

Summary

• accept compact single-channel Viofo filenames like YYYYMMDDHHMMSS_NNNNNN.MP4 alongside the existing channel-suffixed format
• default suffix-less recordings to front-camera/normal metadata
• derive queue day grouping from recorded_at so compact filenames do not produce malformed dates

Background

Some Viofo units expose recordings in their web listing without date/time separator underscores or a camera suffix. Those files were skipped because the filename parser only accepted the newer YYYY_MMDD_HHMMSS_NNNN[FRTI].MP4 style.

Tests

• PYTHONPATH=. .venv/bin/python -m pytest tests/test_queue_filename_parsing.py tests/test_queue_day_grouping.py tests/test_scanner_compact_filename.py

Thanks for this. What model is your camera? Does the GPS extraction work?

[nittanygeek]

A119 mini 2, and yes GPS extraction works.

I had a lot of other changes in the pipeline so have incorporated the single channel filename pattern from your PR into the dev branch rather than merged. Would you be able to test the dev version with your camera? It would also be great to know if the new GPS triage feature works on your camera as well
