Pull request overview
Fixes a regression in UltraPlot’s boxplot wrapper where repeated boxplot() calls on axes with stronger x-axis sharing (sharex >= 2) could accumulate duplicate fixed tick labels, causing duplicated/bold x tick label rendering. Adds a regression test for the reported scenario (issue #628).
Changes:
- Add shared-axis detection for boxplot tick management and bypass Matplotlib’s appending tick-manager on shared tickers.
- Install fixed tick locator/formatter once per call for shared axes to prevent duplicated tick labels.
- Add a regression test ensuring shared x axes do not end up with duplicated tick label text.

This fixes the shared-axis boxplot regression where repeated
boxplotcalls on axes withsharex >= 2could append the same fixed tick labels multiple times, making the x tick labels appear duplicated or bold. The boxplot wrapper now avoids Matplotlib's appending tick manager on already shared axes and applies the intended tick labels once, with a regression test covering the reported case. Closes #628.
