BUG: porousBafflePressure: fixedJump entries are not read

See the missing dict entry in the ctor: porousBafflePressureFvPatchField.C#L59

The entries being not read by porousBafflePressure include (but not limited to):

jump
jump0
value
minJump
relax

    jump_(p.size(), Zero),
    jump0_(p.size(), Zero),
    minJump_(dict.getOrDefault<Type>("minJump", pTraits<Type>::min)),
    relaxFactor_(dict.getOrDefault<scalar>("relax", -1)),
    timeIndex_(this->db().time().timeIndex())
