For now just gonna treat this as a step by step thing since getting web support means doing a whole bunch of separate things because of how I did things.

Storage still needs to be redone a lot because it was sorta coupled in it's own package to share with other things when it should have just been values that were passed down to the repos.

Notifications are annoying because even though it works for web I've just been using topics and web doesn't support topics, so I'll put web on hold till I can get a backend working using FCM tokens instead of using topics.

Lastly the storage commit is going to be reverted because it broke the switches and checkboxes for notifications since they don't update the UI right away. And that also has to do with the first half.
