feat: add temporary dashboard that just shows a user's firebase bearer token and uuid for api testing

[PyDev19]

Why:

• Getting the bearer token is usually a pain because you have to add a temporary await and console.log in some random place to print out your bearer token and constantly refresh the page when that token expires
• After the current login, there is no redirect to a helpful page as dashboard doesn't exist, so this a perfect place for a temporary testing page.

Changes:

• add a dashboard page that shows your bearer token and UUID for API testing purposes
• refresh button on that page to replace your bearer token instead of refreshing the whole page
• safety checking to make sure you are actually logged in

Safety concerns:

• None, the bearer token should only be decodable from the correct Firebase Admin's instance, which is only on the backend

Important Note

• Do NOT merge this into main, it is for testing only, keep it on dev until a replacement dashboard comes through
