feat: split AI Input Agent into Copy/Type Agent submenu with settings

Renames the sidebar entry to "AI Copy/Type Agent" with Copy Agent, Type
Agent, and Settings sub-pages. Settings shows the server's LAN IP
address (via a new /api/ai/network-info endpoint) since it changes
depending on which office the app is running in.
