lloydandClaude Opus 5.5 6a91164a5b Issue #144: automatic value axes scale like Office ...

The value axis used a generic "nice" scale: about five intervals and no
headroom, so data with a maximum of 42.1 got 0-50 in steps of 10, while
PowerPoint and LibreOffice draw 0-45 in steps of 5.

`auto_scale` now follows the rule Office documents for automatic limits:
the maximum is the first major unit at or above max + (max - min)/20, the
minimum is zero when all values are positive and the smallest is below 5/6
of the largest (otherwise the first major unit at or below min - the same
headroom), and all-negative data mirrors that. The major unit is the
smallest 1, 2 or 5 x 10^n that gives at most 10 intervals. Fixed
`<c:min>`/`<c:max>` limits are kept as they are and no longer get rounded
or padded; values beyond them stop at the plot edge. 100% charts get
0-1 in steps of 0.1.

Fixes #144
