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?

A119 mini 2, and yes GPS extraction works.
