Skyler Lehmkuhl 6e6feaddf5 Fix FLAC export end-to-end (real backend path) + smart tag defaults
The prior audio-tags commit put real FLAC + metadata into export/audio_exporter.rs
— which turned out to be dead code (declared, never called; whole file was
EngineController::start_export_audio → daw-backend's export_audio, which still
routed FLAC to the erroring hound stub — hence "not implemented in daw-backend".

Move the work to where export actually happens:
- daw-backend/src/audio/export.rs: real ffmpeg FLAC (16-bit S16 / 24-bit S32,
  skipping the trailing empty flush packet the FLAC muxer rejects); apply_metadata
  on MP3/AAC/FLAC output; RIFF LIST/INFO chunk appended to WAV. New metadata field
  on the backend ExportSettings, threaded from the UI in run_audio_export. Tests
  assert real fLaC magic + round-tripped tags, and a valid WAV INFO chunk.
- Delete the dead export/audio_exporter.rs (removes the duplicate FLAC impl).

Smart tag defaults (filled only when empty, never clobbering edits):
- Year → current civil year, computed from the system clock with i64 math (no
  date crate; correct past 2038/2106 — tests cover post-i32/u32 timestamps).
- Artist → last-used value, else the OS username ($USER/%USERNAME%).
- Album → last-used value.
Last-used Artist/Album persist in AppConfig and prefill next export.
