ℹ️ Issue

Closes

📝 Description

Regenerates application migration with the bare minimum new enums needed for it to work. Also removed the old migration tables

✔️ Verification

\dt and \d application show the correct output

bhchp=# \d application

🏕️ (Optional) Future Work / Notes

The old enums are still at the old values: that will be worked on in a future ticket.
The seeding for applications is still commented out because the enums are operating with new values - which the types are to also be updated in that same future ticket, but for now they are still commented out.
