Enhance UI in Test Scenarios Editor

Test Scenarios editor needs to be polished:

• Delete Buttons are too small - it would be good to enlarge them. done with PR
• Some other elements doesn't have enough space around them.
• Please do any other small visual changes which makes sense.
  • Introduced two new tabs. resolved by PR
    • One shows information about fired rules during scenario run
    • Second enables to configure, kie base/session, allowed rules, date and time used in scenario
