[FRONTEND] Load current user from localstorage if exists

Is your feature request related to a problem? Please describe.

Right now we wait for authentication on the firebase side which is OK but that means that there is a noticable delay when the page is refreshed. A solution would be to keep the user token and details in local storage and load them when firebase first starts up

This one doesn't actually work too well, needs more investigation into the best way to do this

Probably not worth effort at this point
