feat: 球队实体一致性 — 归一化咽喉 + team_aliases 别名机制

events/standings 创建 Team 前均经 team_names.normalize(已有,确认),
TeamRepository.get_or_create 收敛为归一化唯一咽喉 + info 日志。

新增 team_aliases 表(NFKD 归一别名 → teams.id FK CASCADE),
定位三步链:normalize(name) → teams.name → team_aliases → insert。
不自动合并历史重复队;提供 POST /api/v1/admin/teams/aliases 显式添加。

迁移 0020_team_aliases + Admin 别名管理端点(admin_teams.py)。
全量测试 270 通过。
