DAO: Add .chroma file I/O and TrackFingerprintDao wiring

This commit implements reading, writing, and deleting `.chroma`
binary files directly to disk, avoiding BLOBs in the SQLite database.
It also wires TrackFingerprintDao into the broader DAO ecosystem
and adds file cleanup cascades into the central track purging logic.

Changes:
- trackfingerprintdao.h/cpp: Accept UserSettingsPointer to manage
  paths privately in ~/.mixxx/fingerprints/ and add save/load/delete.
  saveChromaFile uses a write-temp-then-rename pattern.
- trackdao.h/cpp: Add TrackFingerprintDao dependency and loop over
  purged tracks in onPurgingTracks() to call deleteChromaFile().
- trackcollection.cpp: Initialize m_trackFingerprintDao with pConfig
  and pass to m_trackDao.
- libraryscanner.h/cpp: Add TrackFingerprintDao member to satisfy
  the updated TrackDAO constructor dependency during background scans.
