Reward Configuration - Githubissues

Rewards configurations can now be uploaded to supabase when creating an event. The organizer can upload the reward name (singular and plural), reward tiers, and reward icons. Here are some of the changes

First navigate to the create event page of the web app
You will see text boxes to the right where organizers can input the reward name (singular and plural), reward tiers, and reward icon
Test this by creating an event with all of its information filled out (don't forget to upload a banner because it will respond with an error)
After creating the event, navigate to this supabase link Link and check if the event is created with the rewards configurations.
Also check out the storage tab on supabase to see if the reward icon is uploaded.
This PR also fixes the create event bug where nothing was being uploaded to supabase after the event was created.
