Update dashboard to design v122 (Part 1)

[somebody1234]

Pull Request Description

• Close Update the Dashboard to Newest Design #9886

  • Update style of buttons in Drive Bar
  • Move "Home" page into a "Start" dialog
  • Remove icons that are no longer needed
  • Remove Backend Switcher in top bar - they have now been converted to categories

• Incidental changes

  • Refactor Backend provider so that both Remote and Local backends are available.
    • This was done because both Cloud and Local backends are now easily accessible by switching tabs - the Local backend no longer has its own views with the hidden category switcher

Important Notes

None

Code review tips

• There are a lot of changes in Settings components, for example (and in general, any component that needs to use a backend). However, most of the changes are identical, so only the approach needs to be reviewed - although the settings pages and the other pages should probably be reviewed separately.

Testing instructions

• Make sure new/changed features work, as mentioned above (drive bar, start page, drag-n-drop)
• Because of the backend changes, all flows in general should be checked, at least at a basic level:
  • Sign up/sign in
  • Offline mode (bottom link on login screen on desktop app)
  • Checking that all settings pages work, both when logged in and not logged in

I guess I'll avoid stacking the move to tabs on top of this PR, as this is a big PR so there may be a lot of changes needed.

1. This loader is barely moving when running cloud project

2. After cmd+r when having project open in progress I no longer see calls projects/<project_id> so I had to reload again to gain access to opened project

weird, i seem to be able to reproduce on develop. seems like it might be a regression

ah. i guess we should store the "currently open project" immediately when the user clicks play, rather than after it actually opens. it's late though so probably won't be fixed today (and possibly will fix on the tabs PR instead.)
