feat: oauth login

[eldu]

• Adds Oauth, restrict to brown.edu
• Makes add pub only available after logging in
• refactors nav bar

After this PR goes through need to go back and edit the firebase rules to the following to ensure only logged in users can write to the firebase

    match /publications/{document=**} {
      allow read: if true;
      allow write: request.auth != null;
    }

⚠️ This PR doesn't restrict to a CCV group. Only to brown.edu

The following code would have let us see a user's groups. However, I hit a 403. It's possible that the Google Workspace administrator has not granted the necessary permissions for your application to access the groups.

// provider.addScope(
//   "https://www.googleapis.com/auth/admin.directory.group.readonly"
// );
const collectionName = 'publications';

export const handleLogin = async () => {
  try {
    await signInWithPopup(auth, provider);
    // const credential = GoogleAuthProvider.credentialFromResult(result)
    // const token = credential.accessToken
    // const user = result.user

    // const response = await fetch(`http://admin.googleapis.com/admin/directory/v1/groups?userKey=${encodeURIComponent(user.email)}`, {
    //     headers: {
    //       'Authorization': `Bearer ${token}`
    //     }
    // })
