Add logarithmic scale, custom labels, and fixed-point number formatting

Browse Source 
- New Linear/Log mapping toggle; log mode uses geometric major-tick
  values with log-positioned minor ticks (validates min/max > 0)
- Optional comma-separated custom labels that override the calculated
  numbers and set the label count
- Format numbers in fixed-point at 4 significant figures (no more
  scientific notation like "1e+04"), snapping log-scale FP drift to ints
- Bump version to 0.75
