Deploy Blocker Analysis

Causing PR: [Payment due @abzokhattab] Add the join-workspace onboarding intent and Concierge follow up tasks (high confidence). This is a frontend bug in App, not a backend issue.

Root cause: That PR added a back button to the work email screen for the join-workspace intent. The button only navigates back to the Purpose screen. It doesn't clear the onboarding error state. The Purpose screen then shows the leftover domainControlledSubtitle error but translates it without the email, so the text reads "undefined is a domain controlled login…".

Recommended fix (roll forward, no revert needed): Clear the error state in the back handler at BaseOnboardingWorkEmail.tsx:365. The file already imports clearOnboardingMergeAccountBlocked.

onBackButtonPress={() => {
    clearOnboardingMergeAccountBlocked();
    Navigation.goBack(ROUTES.ONBOARDING_PURPOSE.getRoute());
}}

If the fix can't land quickly, revert the PR instead. It's large and was already reverted and re-landed once, so a one-line fix is the safer choice.

Investigation details

AddWorkEmail fails with the domain-controlled error. The app saves the key onboarding.mergeBlockScreen.domainControlledSubtitle and sets isMergingAccountBlocked: true (Session/index.ts:1786-1793).
That translation needs the email passed in: (workEmail: string | undefined) => ... (en.ts:3645). The blocked view passes it correctly (OnboardingMergingAccountBlockedView.tsx:42-44).
The blocked view's Confirm button clears the error (BaseOnboardingWorkEmail.tsx:274-278). The new back button skips that step (BaseOnboardingWorkEmail.tsx:363-368).
The Purpose screen translates any leftover error with no arguments (BaseOnboardingPurpose.tsx:253), so workEmail becomes undefined.

Why it happens only on staging: The domain-controlled message and the Purpose error line are already in production. Before this PR, the work email screen had no back button, so you couldn't reach Purpose with the error still set.

Other notes:

The fix also stops other onboarding errors (2FA, SSO, closed account) from showing up on Purpose after a back press.
The issue expects the domain (applause.expensifail.com), but the message inserts the full work email. That matches what the blocked view already shows.
I didn't reproduce this in a browser. The analysis is based on the code.

Next Steps: Reply with @MelvinBot implement this to create a draft PR, or @MelvinBot <your feedback> to refine this analysis.
