feat(roundtable): 业务链条「发布为公共」+ 我的/公共筛选

后端：roundtable_chains 加 is_public 列；list_chains 支持 scope=mine|public（public=所有已发布，任何账号可查看/选入研讨）；get_chain 放开公共可见；响应加 is_public/is_mine；update 支持 is_public（发布/取消，owner 限定，编辑/删除仍仅 owner）。迁移 20260608_03 接在合并 head 20260608_02 之后，保证单一 alembic head（多 head 会让启动自动迁移失败、静默降级 create_all → 列缺失 500）。

前端：listChains(scope) + setChainPublic；BusinessChain 加 isPublic/isMine；列表弹窗与研讨选择器加「我的/公共」筛选 tab；列表卡片发布/取消发布 + 公共徽标（别人的只读）；配置页头部加发布按钮（已保存且本人）。
