fix(creator): 修复导入页列表 SQL —— join 缺别名导致 /accounts/import 一进来就 500

- ListCompetitorShareJobsWithAuthor 的 LEFT JOIN creator_competitor 缺 AS competitor
  别名，ON 条件引用 competitor.id 直接报 missing FROM-clause entry（42P01）
- competitorShareJobFilter 过滤条件误用原表名 creator_competitor_share_job，
  与查询别名 share_job 不符，带 platform/status 参数时会再报缺列
- 新增集成测试 TestListCompetitorShareJobsWithAuthorSQL 覆盖 join 作者回填
  与 platform/status 过滤（此前该 SQL 无任何测试，bug 逃逸）
