feat(backend): add user custom attributes system
Add a flexible user attribute system that allows admins to define custom fields for users (text, textarea, number, email, url, date, select, multi_select types). - Add Ent schemas for UserAttributeDefinition and UserAttributeValue - Add service layer with validation logic - Add repository layer with batch operations support - Add admin API endpoints for CRUD and reorder operations - Add batch API for loading attribute values for multiple users - Add database migration (018_user_attributes.sql) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
