Add tooltip to port forwarding rules showing relay host details

[Copilot]

Port forwarding rules display minimal info (127.0.0.1:xx -> 127.0.0.1:xx) without indicating which relay host is used, making tunnels hard to distinguish.

Changes

• RuleCard.tsx: Added host prop and wrapped summary in Tooltip showing:
  • Relay host label and full address (user@hostname:port)
  • Forwarding type description (local/remote/dynamic)
• PortForwardingNew.tsx: Pass host lookup to RuleCard
• i18n: Added tooltip translations for en and zh-CN

Example tooltip content

Relay Host
Host: my-server
Address: admin@192.168.1.100:22
─────────────────────────
Local port forwarding: Access remote services through SSH tunnel

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.electronjs.org
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/Netcatty/Netcatty/node_modules/@electron/rebuild/lib/module-type/node-gyp/worker.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>[Feature]:希望端口转发也支持分组或展示更多信息</issue_title>
<issue_description>端口转发目前展示的数据 还是太少,没显示中转主机的 IP
比如只转一层的话 可能显示的就是 127.0.0.1:xx ->127.0.0.1:xx 看不到具体哪个主机
再一个 能不能增加分组 方便管理 </issue_description>

<agent_instructions>根据目前的设计 应该装不下这么多信息，考虑用tooltip实现这个用户说的信息展示的方式</agent_instructions>
