Prioritize deeplink navigation before event publishing

ENG-0003: Code Reviews Guidelines

What changed? Why?

Reordered deeplink navigation to execute before publishing web3 request events on mobile web. This change addresses Safari's popup blocking behavior by ensuring the deeplink opens within the user interaction context.

The key change:

• Moved openCoinbaseWalletDeeplink call to execute immediately when a web3 request is initiated on mobile web
• The event publishing now happens asynchronously after the deeplink navigation

How was this tested?

Manual testing on mobile Safari to verify deeplinks open without being blocked by the popup blocker.

How can reviewers manually test these changes?

1. Open the test app on mobile Safari
2. Connect wallet and trigger any web3 request (e.g., sign message, send transaction)
3. Verify the Coinbase Wallet deeplink opens immediately without Safari's popup warning
4. Confirm the web3 request is still processed correctly after navigation
