[Feature Request] Show real-time connection stats and IP before/after connect #26

Hi,

Two small features would make the home screen much more useful:

1. Real-time connection stats

• Download / upload speed
• Total data used (session + monthly quota remaining)
• Ping / latency
• Connection uptime

2. IP before / after connect

• Show the real IP (and country) before connecting
• After connecting, show the new IP and country
• This is the fastest way for users to confirm the VPN actually works, and it helps when testing different pinned edge IPs

Both can be compact — a small card on the main screen is enough. Even just IP before/after would be very helpful for debugging and for confirming the location matches the selected country.

Thanks.
