/*
  # User Features Migration

  1. New Tables
    - `user_profiles` - Track user onboarding and additional info
    - `additional_emails` - Store additional email addresses per user
    - `email_processing_usage` - Track email processing usage

  2. Security
    - Enable RLS on all new tables
    - Add policies for user-specific data access

  3. Performance
    - Add indexes for optimal querying
