feat: KOOK自动获取bot身份 + action/narration剥出气泡 + 渠道配置表单回填

agent-116 KOOK token即用+自动获取:
- kook/identity.go: Connect 调 GET /user/me 拿 bot 身份(bot_id/bot_username/bot_nickname), 失败容错
- 渠道列表 enrichAccountsWithBot 附 bot 身份; base_url空用默认/receive_mode默认ws(只填token可跑)

agent-117 action/narration 剥出气泡(主人需求: 动作/旁白不进气泡,按位置上/下):
- parseContent.splitBubble(content)->{body,head,tail}: body=纯文本(去标签), head=开头/中间action/narr(气泡上), tail=结尾(气泡下)
- renderContent 只渲染text(去内联灰斜体); chat.tsx BubbleNotes 泡外 ＊动作/旁白＊ 灰斜体小字(气泡外依附), SplitChatBubble 先剥splitBubble再splitParagraphs(body), <p>/\n\n/毛玻璃/SourceLabel不破坏
- 注: 非chat mode renderContent 现在丢弃action/narr(可接受)

Channels 配置表单回填(修save后输入框空):
- openConfig 从 data.accounts[0].config 回填 token(掩码提示)/base_url/平台字段/黑白名单/限流, 不再硬清空
