fix: realistic sinus + continuous pump control + dead zone elimination
Some checks failed
CI / lint-and-test (push) Has been cancelled

Sinus inflow: 54-270 m³/h (base 0.015 + amplitude 0.06 m³/s), 4 min
period. Peak needs 1-2 pumps, never all 3 = realistic headroom.

PS control: continuous proportional demand when level > stopLevel, not
just when > startLevel && filling. Pumps now ramp down smoothly as
basin drains toward stopLevel instead of staying stuck at last setpoint.
