Added tests for Video & Audio

feat: video/audio metadata scanning, profile rename fix, route tests

  - Scan .mp4/.mov/.avi/.mkv and .mp3/.flac/.ogg/.m4a/.wma (+ 7 more)
    for GPS coordinates, artist/author, title, comment — metadata only,
    no frame or audio analysis. Uses mutagen (added to requirements.txt).
    GPS-tagged phone recordings now flag with gps_location like photos.

  - Fix _extract_audio_metadata silently returning empty results:
    mutagen.File() first positional arg is `filename`, not `fileobj` —
    was passing BytesIO as the filename. Fixed to keyword args.

  - Fix profile copy rename not reflected in left column until modal
    reopen: _pmgmtSaveFullEdit called loadProfiles() but never
    _renderProfileMgmt(). Added re-render and active-row highlight.

  - Add TestProfileRoutes (10 tests) covering all profile API endpoints
    including a rename regression test. Total: 182 tests.

  - generate_fixtures.py now produces 6 audio/video fixtures (14–19):
    2 MP3, 2 FLAC, 2 MP4 — 4 flagged, 2 negative cases.
