The previous auto-preamp computed db_to_linear(-max_positive_gain),
multiplied the entire wet signal by it, and cancelled the very boost the
user asked for. A +12 dB bass slider ended up with 60 Hz at roughly 0 dB
and everything else attenuated, which made bass feel lighter.

Keep the biquad crate and the 5-band peaking EQ; just drop the internal
auto-preamp and rely on the downstream soft limiter for peak control.
This makes each band gain an absolute dB boost/cut as users expect.

Update the playback contract and locale strings to match.
