Feature/expose pilz sampling time

[riv-tnoble]

Description

#3330 aims to add spatial-based trajectory sampling to the pilz planners, but work on it seems to have stopped. Currently, pilz uses a hard-coded 0.1s sampling time which is unsuitable for fast robot motions. I think it'd be worth reviving the referenced PR but, as a quick improvement, this PR exposes the sampling time via a new parameter.

The added parameter defaults to 0.1 to preserve the existing behaviour, and should be extensible to adding spatial parameters in the future. I've also done a bit of renaming of references to the existing cartesian limits parameter in the code for clarity.

Checklist

• Required by CI: Code is auto formatted using clang-format
• Extend the tutorials / documentation reference
• Document API changes relevant to the user in the MIGRATION.md notes
• Create tests, which fail without this PR reference (Existing tests updated to preserve prior behaviour)
• Include a screenshot if changing a GUI (N/A)
• While waiting for someone to review your request, please help review another open pull request to support the maintainers

The non-humble pipelines appear to be failing for reasons that seem unrelated to these changes. @nbbrooks are these known issues? (Sorry to ping you randomly. Noticed you were looking at Qt6 stuff)

I see you merged in the latest main changes for Qt6, let me retrigger the job again and see what happens.
