Added comprehensive user profile columns to fix 400 Bad Request errors:

Profile Information:
- bio, phone, location, website
- phone_number, recovery_email, recovery_email_verified

User Preferences:
- language (default: 'en')
- theme (default: 'dark')

Notification Settings:
- notifications_email (default: true)
- notifications_push (default: false)
- notifications_sms (default: false)

Security:
- two_factor_enabled (default: false)
- email_verified (for compatibility)

Metadata:
- joined_at (synced from created_at)
- role (default: 'Member')

This resolves 400 errors when updating profile settings.
