feat(search): extract more data from tika 4 (if available)

[dschmidt]

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

Splits the tika extractor and its tests into per-facet files and fills the facet properties Tika 4.0.0 exposes:

• Audio: bitrate, isVariableBitrate, hasDrm, trackCount, discCount, copyright, composers
• Location: altitude (EXIF GPS, metres → feet)
• GPS now also resolves for videos (MP4/MOV)

Works against Tika 3 and 4 at the same time: full text is read from tk:content with the legacy X-TIKA:content as fallback (4.0.0 renamed the meta prefix), and language detection for stop-word cleaning asks /language first with the legacy /language/string as fallback (4.0.0 moved the endpoint, go-tika only knows the old path). The new facet keys only exist on Tika 4, an older Tika simply leaves those facets empty. The acceptance suite runs against the released apache/tika:4.0.0-full; CI sets the tika service workdir to /opt/tika-server since Tika 4 discovers its plugins relative to it (TIKA-4864).
