fix(denoise): work around dask 2024.12 passing removed interpolation kwarg to numpy 2.x

Dask 2024.12.1's _nanquantile_1d_or_missing passes interpolation=None
to np.nanquantile, which was removed in numpy 2.x. Use skipna=False
to avoid the nanquantile code path entirely, filling NaN values before
computing the quantile instead.
