#5858 - fix: Timeline node width made dynamic

[afmireski]

📑 Summary

In timelineRenderer, the width of the timeline diagram nodes is hardcoded, making width configuration changes ineffective.

Resolves #5858

📏 Design Decisions

Extract the hardcoded value, defined here, into a constant and use it as the default if the node width is not specified in the timeline configuration.
I've added tests to verify the application of both the default and custom widths.

Hello,

Looking at the test workflow failures, I noticed that the tests passed:

The error seems to be related to insufficient storage for saving Cypress screenshots:

Is there any correction I need to make?

I also noticed that Codecov reported a lack of coverage, but my integration tests appear to be running correctly. I would greatly appreciate any suggestions or feedback you can provide. I'm a newbie in open-source.
