feat: 实现域能系统

- 新增域能完整分层：EnergyLog/PostEnergizeLog/DailyExpSummary 模型、EnergyRepo、EnergyService、EnergyController/AdminEnergyController
- 支持签到获取域能(+1)、帖子赋能(-1/-2)/被赋能(+1/+2)、改名扣能(-6)/退款(+6)、删帖扣能(-2)
- 赋能单人单帖上限20域能，每日赋能获得经验上限50
- 管理员支持批量调整域能(owner)和查询域能日志(admin)
- LV0用户(exp<1)禁止签到和发帖，余额为负可签到/被赋能/删帖但不能赋能/改名
- 首次改名免费(通过HasCompletedTask判重)，改名扣能在提交审核时执行
- 移除导航栏手动签到按钮，签到融入域能系统(自动签到)
- 新增个人中心域能TAB展示余额和流水日志(近7天)
- 新增帖子详情页赋能按钮(轻赋/重赋)
- 管理后台新增域能管理和域能日志页面
