Reset migrations and created a seeder folder in the backend with the initial experiences/treatments/qualities/roles/forms

[YashK2005]

Hack the North pt. 1

Next steps: for the intake forms - updating the seed data with the new experiences/treatments if needed, fetching the experiences from the backend rather than hardcoding them in the frontend, having a system so that cancer patients and caregivers are shown different experiences.

After that I will probably work on the participant dashboard.

The designs for the forms are slightly updated now so that should also be changed (will leave this for later in the term)
