refactor: 合并 identity-service migrations 为单一 init

将 7 个碎片化的 migration 文件合并为一个完整的 init migration：
- 删除增量 migrations (add_user_totp, add_outbox_events, add_password_hash 等)
- 创建统一的 20241204000000_init migration 包含所有表结构
- 包含所有索引、外键约束、序列设置和系统种子用户

--- CreateSystemSeedUser: 创建系统种子用户作为根推荐人

--- 已经预留了 user_id 1-9 给系统账号，所以这里使用 ID 1 是安全的
