Regressions

The diff is quite large so there's a good chance that this breaks things. I tried to test everything but I'd still like you to do some monkey testing yourselves. I also updated the e2e tests.

Notes for Reviewers

• Like last time, it's necessary to update the config variables to mount this in development mode:

export export TTN_LW_IS_OAUTH_UI_JS_FILE="libs.bundle.js account.js"

• Like last time, this PR targets feature/1422-account-app which I keep rebased on latest minor. When all parts are added, we will merge this branch into the minor.
• I put the update password integration tests on skip() since I had to remove the password updating when logged in for now. I will reintroduce it in the upcoming PR, which will add the groundwork for the new authenticated views
• I missed renaming the static assets from account-*.* to oauth-*.* in the last PR. This is necessary to ensure config compatibility. I'll fix this in another PR, since there will also be some changes to the branding/assets itself.

1. Reset password view does not show an error when non-existent user id is provided
2. Update jsconfig.json paths to account for the new account folder
3. If I navigate to /oauth/anything I end up on a broken screen without any errors
