Feat: Event View Backend

[OdeYec]

Improved backend of the get method endpoint of "eventview" to show actual event details instead of placeholders.

On the way:

• Fixed up get_event_by_id (previously by_id), including error handling
• Fixed delete_event and update_event to fit new get_event_by_id function
• Moved logger to dependencies so can be used outside of main
• Fixed up the event_test_client
• Added and fixed up event tests
