feat: add proxy settings UI under Comfy > Network

Add three new settings for configuring HTTP/HTTPS proxy:
- Comfy.Network.Proxy.HttpUrl — main proxy URL for all traffic
- Comfy.Network.Proxy.HttpsUrl — optional separate HTTPS proxy
- Comfy.Network.Proxy.NoProxy — hosts to bypass proxy

Settings appear in the Settings dialog under Comfy > Network.
Values are persisted to comfy.settings.json and read by both
the Python backend and the Electron desktop app on startup.
