🐛 Bug Fixes

• Water Percentage (Dual Mode): Corrected the displayed water percentage in
  S400 dual-frequency mode. The Deurenberg formula was producing physiologically
  implausible values (>90% for BMI <28), which were then clamped to 73%. The
  displayed percentage now consistently uses the Pace & Rathbun (1945)
  constant ((100 − fat%) × 0.73), expressing TBW as a percentage of total
  body weight (~55–65% typical range) rather than an inflated figure. The
  underlying Deurenberg TBW liters are still used internally for ECW/ICW/BCM
  compartment calculations. (Fixes #360).

• Skeletal Muscle Mass (Standard Mode): Fixed an issue where
  skeletal_muscle_mass was incorrectly exposed as an attribute in standard
  (single-frequency) mode. This metric now only appears in dual-frequency
  mode.
