feat(search): extract more data from tika

[dschmidt]

Stacked on #3197 (search schema-change handling).

Draft: needs the unreleased Apache Tika 4.0 (pinned by snapshot digest) for the new metadata keys.

Bumps libre-graph-api-go, splits the tika extractor and its tests into per-facet files, pins the acceptance tika to a 4.0.0 snapshot, and fills the facet properties Tika 4.0 now exposes:

• Audio: bitrate, isVariableBitrate, hasDrm, trackCount, discCount, copyright, composers
• Location: altitude (EXIF GPS, metres → feet)
• GPS now also resolves for videos (MP4/MOV); the Content-Type: audio/ gate is gone, so audio metadata is read from any file.

The libregraph bump lands here as the foundation for the follow-up motion-photo and live-photo PRs (kept separate, they are non-trivial), so those stay smaller and don't have to re-review the vendor changes.
