Psychotoxical 42a84932e6 fix(audio): restamp playback position across active/neutral rate toggles

The sample counter maps to song position via a factor of `speed` while the
preserve-pitch effect is active and 1.0 while neutral. A change that flips
active<->neutral (enable/disable, or speed crossing 1.0x) therefore needs the
counter restamped to hold the position — but the condition only fired for
active->active speed changes. So every enable/disable toggle reinterpreted the
counter under the new factor and jumped the position (~raw_secs x dspeed —
e.g. +-18 s at 180 s on a +-10% toggle).

This broke Orbit drift correction, whose bang-bang nudges toggle the effect
on and off with the full +-10% delta. Extract the decision into
`rate_change_needs_restamp` and fire it on any active<->neutral transition (and
active->active speed changes), always re-deriving the counter for the new
config. Tests cover the condition and the position-stable invariant.
