Martino Ferrari ed71719df7 fix(math): keep from_range invertible for collapsed pixel spans ...

A zero pixel span previously produced sx/sy == 0, so to_data_* returned
NaN or +/-inf. axis_scale now substitutes a unit pixel span (1.0) when
|p1 - p0| <= 1e-12, keeping the mapping finite and invertible while
leaving non-collapsed spans byte-identical.

Add committed coverage for from_range (linear, flipped pixel axis, log x,
degenerate data range, collapsed pixel span) and log10_positive clamping.
