S12: store wall-clock ADSR/pitch-env as seconds, resolve to frames at live rate

Kill kTier0Nominal*, adsrNeedsRateResolve, tier0Adsr, gateAdsr. Zones payload v5 carries
seconds; v3 legacy reads convert at the frozen authoring rate; v4 (branch-only) dropped.
Editor sliders now seconds. Engine takes frames resolved at keymap build.
