fix: use baseUrl for Socket.IO connection to support separate frontend hosting

Previously, useTerminalSocket used a relative path `/terminal` for Socket.IO,
which would connect to the frontend host instead of the actual HAPI server.
Now it uses the baseUrl from context to connect to the correct server, enabling
scenarios like hosting the frontend on GitHub Pages while the server runs elsewhere.
