Context behind the change

The previous custom wallet modal was limiting the connection UX and required us to maintain wallet-specific UI logic ourselves. Replaced it with Reown AppKit so users get a more standard wallet-selection flow while we keep the existing wagmi-based code unchanged.

How has this been tested?

Ran dashboard locally.

Release plan

Add new VITE_APP_TERMS_URL and VITE_APP_PRIVACY_URL with terms and privacy policy URLs

Potential risks; What to monitor; Rollback plan

We don't use reown because we can't customize connection popup to fit our design (esp. new one)
I'm not. agains using it, but would suggest that we get back to it once redesign is finished, unless @KirillKirill has some other info related to it

I started integrating it yesterday because it was requested, and after testing it I think it may be worth keeping. Our current modal only supports 3 wallets, while Reown supports many more out of the box, which is much better for users. Also, it's customizable, so we may be able to adapt it to the redesign instead of maintaining our own custom modal.
