Review of testing artifacts for Spring26

[rartych]

Problem description
The new Commonalites release ( currently prepared 0.8.-rc.2) brings changes in Guide documents and common artifacts.
Testing artifacts were reviewed partially, in consequence some proposed test scenarios may follow the outdated guidelines.
One example is: new pagination guidelines applied to event subscription template.

Expected behavior
Checking the testing artifacts for the changes introduced in Commonalities and proposing needed corrections.
Wiki page Analysis of Commonalities 0.8.0-rc.2 may be helpful.

Alternative solution

Additional context
The update should be prepared before public release of Commonalities.

@rartych what about rewriting (or writing) test definitions which fit to the sample API templates? Some additional ones, like the device test cases are in addition still valid.
