feat: hook up firebase + create leaderboard

[jcuadrosj]

Sorry for the long PR.. it ended up piling up..

Changes:

• Add Firebase to the codebase
• Create config + api file where I centralize functions to read/write/subscribe to the db
• Adds Button component with two variants: primary and secondary (open to changing this, or feel free to update as needed, there's some TODOS's for stying but I think that once we figure out the theme it will all come together).
• Adds Modals with different variations. This takes the place of 'reset' component. Here is a list of the modals created:
  • Invalid Board -- shows when Bingo pattern is not met
  • Login modal -- shows when when user gets bing for the first time
  • Update Username -- shows ofter the user's first login (note: there's also a users component that allows the user to update the username -- this one needs to be updated, there's also a TODO in there).
  • This has a randomNameGenerator method that calls a cloud function to generate a random name given some terms we provided.
  • Modal also has a checkbox to be able to 'opt in' to marketing emails
  • Submit score -- Shows when the user submits a score and is already logged in.
• Adds leaderboard component -- this subscribes to changes in the db so it updates in real time
• Adds Logout menu item to the BurgerMenu component

Notes

I know this is a lot, happy to walk through this, let me know a time that works best!

@alexsharp4096 I (finally 🙈) got my changes up. If possible, take a look on your end by running this branch locally! All the functionality mentioned in the PR comment should be working! I'll be trying to work on with GitHub auth today. Let me know if you run into anything

Two Issues:

1. Username not showing on board

   

2. Random name generator not working, both on sign up and on update user
