修复群邀请消息卡片丢弃"立即加入"按钮，被邀请人无法接受邀请
根因：POST /groups/{topic}/invitations 邀请成功后，后端会往邀请人与被邀请人的
单聊会话里发一条 x-im-type=system_action、template=group_invitation_created 的
消息，content.actions 里带着真实可用的 {type:"group_invitation_accept",
label:"立即加入", target_id:<invitation_id>}（对照参考图 6.3 加入群聊.png）。但
chat-message.jsx 原来对所有 system_action/system_notice 消息一律只取
content.text 渲染成纯文本，这个 action 数据被整体丢弃，消息只显示"邀请你加入群聊。"
没有任何按钮——im-api.js 里封装好的 acceptGroupInvitation() 因此从来没有调用点。
怎么修：chat-message.jsx 在原有的文本兜底之前，单独识别 content.actions 里
type=="group_invitation_accept" 的这一种模板，渲染一张带按钮的小卡片（其余
system_action/system_notice 模板的纯文本渲染保持不变，不受影响）；
messages-view.jsx 新增 handleAcceptGroupInvitation，调用 acceptGroupInvitation()
并用已有的 showToast 反馈结果，逐层传给 ChatMessage 的新 onAcceptGroupInvitation
prop。按钮点击后按 busy/joined/pending_approval/error 四态展示，避免重复提交。
验证：用两个真实账号（A 建群，直接对 B 发起 POST /invitations）复现，重新构建后
B 的会话里正确出现"邀请你加入群聊。"+"立即加入"按钮；点击后正确调用
POST /group-invitations/{id}/accept 并把返回的失败原因("服务器繁忙，请稍后重试")
展示出来——这一步暴露了一个独立的后端 500 bug（accept 接口本身的实现有问题，
已记录在测试报告里，不在本次前端修复范围内），前端的请求发起、按钮状态机和错误展示
均已确认按预期工作。
