[backend] Add the default Assets logic to scenario creation and update

[heditar]

Proposed changes

• implemented the logic to automatically add default assets at the creation of injects
• updated the existing api to update simulation/scenario to add the default assets to the injects if the applyRule parameter is passed to the api

-> I didn't not add api tests as I was struggling to make them work, it will be added in a follow up PR

Related issues

• Define and apply default assets for OCTI generated simulation #1998

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality
• I wrote test cases for the relevant uses case
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality
• For bug fix -> I implemented a test that covers the bug
