chore: resubmit OAuth verification for drive.readonly scope

[ummaraali2]

Background

Form Builder currently has the following OAuth scopes
verified by Google:

• userinfo.email
• userinfo.profile
• drive.file
• forms.body

A new feature (open existing Google Form via Drive
picker) requires the drive.readonly scope which is
not currently verified.

What needs to be done

1. Go to Google Cloud Console → Data access
2. Add drive.readonly scope
3. Go to Verification centre
4. Resubmit for verification with justification:
   "drive.readonly is used to allow users to browse
   and open their existing Google Forms for editing
   in Form Builder. The Google Picker API filters
   to show only Google Forms files
   (application/vnd.google-apps.form). No other
   Drive files are accessed or stored."
5. Update demo video to show the Open Form feature
6. Wait for Google approval (1–2 weeks)

Impact

This feature cannot be released to all users until
drive.readonly is verified. During verification
period users will see the unverified app warning
when signing in.

Notes

• drive.readonly is a sensitive scope
• Google will likely ask for a demo video showing
  exactly how the scope is used
• Record a short video showing:
  • Clicking Open Form button
  • Drive Picker opening with only Forms shown
  • Selecting a form
  • Form loading into the editor
• Do not release the Open Form feature until
  verification is approved

Depends on

• feat: open and edit existing Google Form via
  Drive picker
