[TEAM2-377] EIP-4339 Detect Merge With Flag

[derHowie]

What changed (plus any additional context for devs)

I'm throwing up a draft in preparation for the Görli merge 08/10 @ 2pm EST. I've left Ropsten in the app for now as it is a good test case for toggling between networks that have and have not merged.

What to test

Final checklist

• [x] Assigned individual reviewers?
• [x] Added labels? (team1/team2, critical path, release, dev QA)
• [x] Did you test both iOS and Android?
• [x] If your changes are visual, did you check both the light and dark themes?
• [x] Added e2e tests? If not, please specify why
• [x] If you added new critical path files, did you update the CODEOWNERS file?
• [x] If no dev QA label, did you add the PR to the QA Queue?
