Fix X axis labels overlapping

[Dmitrii Sukhankin (dsukhankin)]

Right now, labels on the X axis don't have any logic to prevent overlaps. This PR adds ellipsis to labels that are longer than what should be given to each tick on the X axis.

This PR also fixes package vulnerabilities with npm audit fix.

Pull request overview

This PR updates the DotPlot Power BI visual to reduce X-axis label overlap by truncating long tick labels with ellipsis, and it also applies dependency security updates via npm audit fix.

Changes:

• Apply textMeasurementService.getTailoredTextOrDefault(...) to X-axis tick labels to truncate text to an estimated per-tick width.
• Move tick label formatting from the axis tickFormat(...) path to post-render DOM text updates.
• Update package-lock.json with patched transitive dependency versions from npm audit fix.

• When categoryAxis.show is false, this code unconditionally does .append("title") on every render. If renderAxis() runs multiple times while the setting remains false, each tick text will accumulate multiple <title> children. Prefer updating/replacing the existing title node (e.g., remove then append, or use a data join) instead of always appending.
