refactor(accounts): 移除「授权状态」概念——账号收敛为启用/暂停单一状态机

产品已收敛为自有账号管理，撤销授权在 UI 无入口、状态恒为 authorized，属废弃语义：
- migration 1045：social_account DROP authorization_status/revoked_at/authorization_kind
- 删除 revoke API 路由与 RevokeAccount/disableAccount 状态机分支（PauseAccount 独立）
- accountRunnable/就绪判定/采集过滤/登录校验删除 authorization_status 检查
- EnvironmentContext/AccountProfile 契约删字段；前端删「已授权/已撤销」展示与 readiness 分支
- 测试同步：revoke 流程/409 用例删除，seed 语句去列；dev 库测试遗留 revoked 账号待 UI 删除
