US-006: 验证 + 修复编译和运行时问题

- 修复 migration: role 从 ENUM 改为 VARCHAR(20) 以兼容 tokio-postgres
- 修复 Cargo.toml: 将 chrono/argon2/uuid/rand 改为非 optional，添加 wasm-bindgen/getrandom js
- 修复 main.rs: Tokio runtime panic，改用 std::thread + Runtime::new
- 修复 db/mod.rs wasm stub: DummyPool 替代 deadpool_postgres
- 修复 login/admin.rs: wasm_bindgen::JsCast 条件编译
- 验证通过: 注册✓ 登录✓ get_current_user✓ 重复注册拒绝✓ 错误密码✓
