[Feature]: Improve UX/UI in Eventum Studio

[rnv812]

Preliminary checks

• I searched existing issues and discussions and did not find a duplicate.

Problem

Improving user experience

Proposed solution

• Background and paper panels has the same color - they should be different
• Objects cannot be renamed, recreated only (add possibility to rename project, instance, scenario and other possible objects in a system)
• Add a fast way to open object just by clicking on its title, not by clicking edit in row actions (but keep it possible to select it's name and not being navigated down to it)

Alternatives considered
