feat(admin): add comprehensive admin management system

- Add admin handlers and services for users, posts, comments, groups, and dashboard - Implement role permission management with ability to view and update permissions - Add database seeding for roles and Casbin permission policies - Upgrade Casbin from v2 to v3 with GORM adapter for persistent policy storage - Add admin-specific repository methods with filtering and pagination - Register new admin API routes under /api/v1/admin/*
