s12: thread project rate through v3 legacy lift; remove 44100 literals

kLegacyV3NominalRate removed. readZonesPayload, deserializePerformance, deserializeComponentState now take a projectRate for v3 frames→seconds. Rate fields default 0 (invalid). Four 44100 fallbacks replaced with assert+safe-return. 96k v3-lift test added.
