feat(projects): 服务机构筛选改 IN 精确查询

- BizProject: 加 List<Long> execAdminUserIds (多选 select IN 透传),
  execOrgName 标 @Deprecated (兼容老 API)
- BizProjectMapper: selectList 替换 3 列 OR LIKE (org_name/user_name/nick_name)
  → EXISTS + bpa.exec_user_id IN (精确, 跟 sponsorAdminUserIds 对称)
- BizOrgMapper: selectExecutorOrgOptions 加 LIMIT 5 (跟 sponsor 对齐)
