Only username is required, all other fields (email, phone, public_key, etc.) are now optional.
Changes:
- Modified 001_init_schema.up.sql to remove NOT NULL constraints
- Added partial unique index for email (only for non-NULL values)
- Created migration 006_make_email_optional for existing databases
- Set default status to 'active'
This allows automatic account creation from keygen without requiring user info.
