[Feature] New Building Type Backend

[avayedawadi]

Description

• Ability to build an entirely new building type.
• Admin user should be able to click a button to add a new building type (in addition to the already existing multifamily, single family, and commercial building types) with its own set of cards.
• Need to alter the MongoDB to allow a new building type to be inserted.
• For this ticket, just worry about getting everything set up in the database, and having everything work on a theoretical level on the backend. We will worry about having everything show up nicely in the frontend later. Database and backend refactoring is the bulk of this ticket.
• Contact EM for help as needed, this is a complex ticket. Please ask for extra time as needed if school or life is getting into a crunch.

In the end, the admin should be able to add building types to this page

Acceptance Criteria

• API/Backend for adding a new building type works.
• Database has been adjusted for entirely new building types to be added.
• A new building type can contain its own set of cards.
• Only admin can edit building types

Other Notes

• Right now the building type is just a constant in the way that it is stored in the backend.
• Potentially, the adjustment will need to be made for the building type to have its own schema in order to then be something added to and taken away from the database.
• If you would like to go ahead and get started on the frontend, feel free, but just worry about the backend and the database schemas for now.
