fix: 域能系统全量检查 — 修复 5 个逻辑/交互 Gap

- 修复 Admin 改名路径未扣域能（非审核路径补充 HasCompletedTask + DeductOnRename）
- 赋能按钮改为 Modal 弹窗（轻赋/重赋选择 + 每日上限提示）
- EnergyInfo API 增加 daily_energize_exp/daily_exp_cap_reached 返回值
- "我的域能" TAB 增加经验值和等级展示
- Energize 事务修复：导出 EnergyStore + WithTx 方法确保 DB 操作原子性
- Studio 写文章页新增 LV0 锁止横幅 + 禁用提交按钮
