settings: add the replay gain controls

Final slice: the screen that drives the mode and preamp preferences the
playback side already reads. Until now `setReplayGainMode` and
`setReplayGainPreampDb` had no production caller, so Off and the preamp
were unreachable.

- `SettingsViewModel` exposes both preferences and writes them back.
- The Playback section gains a "Replay gain" row opening an Off / Track /
  Album choice, and a "Preamp" row opening a slider across the +-15 dB
  range in 0.5 dB steps.
- `ReplayGainMode` is ordered Off, Track, Album so the choice list reads
  that way; the stored value is the name, so the order is not persisted
  and the default is still Track.
- The labels live in their own file so the signed decibel formatting can
  be tested, as `formatTrackTime` does.
