more permissive verification process (#4317)
* style fixes ✨ * verification: find last request * verification: don't request again if same input * didRequestWithSameValues -> shallRequestAgain * bugfixes 🐛, update SMS verification ABI * verification: hasRequested -> accountHasRequested * verification: hasIsVerified -> accountIsVerified * verification: shallRequestAgain -> shallSkipRequest * verification: show if unable to send req * email verification: check if email already used * address style grumbles 🎨
