后台新增游戏管理页与全量游戏列表接口

- SpacetimeDB 新增 list_admin_game_distribution_games_and_return：一个事务内返回全量游戏、版本数与最近 20 个版本，作者名/头像读时联 user_account
- SpacetimeDB 新增 restore_game_distribution_game_and_return：恢复管理员暂停的游戏时重新激活最近一次由管理员暂停撤回的公开版本，作者自行下架的版本不会被恢复
- 后台新增 GET /admin/api/game-distribution/games 与 POST /admin/api/game-distribution/games/{gameId}/restore，并新增 game-management Tab 权限，待审队列仍只属于 editor-showcase
- admin-web 新增 #game-management「游戏管理」页：标题/作者/gameId/状态/版本数/游玩数表格，行内下架、恢复与版本历史弹层，复用现有后台表格与二次确认
- 同步生成 spacetime 绑定并更新后端架构数据契约文档
