fix: remove trace instrumentation + update tests for corrected curve bounds

The bogus machineCurve default at pressure "1" (fixed in generalFunctions
086e5fe) made fValues.min=1, which let sub-curve differentials pass
unclamped. With the fix, fValues.min=70000 (the real curve minimum) and
low differentials get clamped. Three tests that accidentally depended on
the bogus min=1 behavior are updated:

- coolprop test: expects fDimension clamped to curve minimum when
  differential < curve range
- pressure-initialization test: uses pressures whose differential falls
  WITHIN the curve range (900 mbar = 90000 Pa > 70000 Pa minimum)
- sequences test: tests upper-bound constraint with setpoint > max,
  then confirms a valid setpoint is applied as-is (was incorrectly
  asserting any setpoint would be clamped to max)

Trace instrumentation from debugging session removed.

91/91 tests green.
