Add Reports to SQL Schema

[nourshoreibah]

User Story

As a BRANCH user, I want reports to access stored reports

Overview

Add the report to our SQL schema in the backend/db folder

Acceptance Criteria

The report table should match this ERD diagram

• It links to project via foreign key, has a primary key, contains an object URL that points to an object in our bucket, and contains the date it was created
• Create mock seed data (can be fake URL for now or can actually put it in our bucket)
