Show permission modal for bank account currency flow

[ShridharGoel]

Explanation of Change

This PR prevents payments admins from being sent to the admin-only workspace currency page from the Workflows bank account flow.

When a payments admin tries to add a bank account for a workspace with an unsupported output currency, clicking "Update workspace currency" now shows a "Not so fast" modal. The modal explains that only bank accounts matching the workspace output currency can be added and asks the user to contact a workspace admin to adjust permissions.

Workspace admins can still continue to the currency page from the same flow.

Tests

1. Sign in as a payments admin for a non-USD Control workspace that has no bank account set up.
2. Go to workspace settings > Workflows.
3. Click Add bank account.
4. Verify a "Not so fast" modal appears with the expected permission message.
5. Click OK.
6. Verify the app stays on the Workflows page and does not show the Not here page.
7. Sign in as a workspace admin for the same workspace.
8. Go to workspace settings > Workflows.
9. Click Add bank account.
10. Verify the workspace currency warning modal appears.
11. Click Update workspace currency.
12. Verify the workspace admin is navigated to the workspace currency page.

• I linked the correct issue in the ### Fixed Issues section above
• I wrote clear testing steps that cover the changes made in this PR
  • I added steps for local testing in the Tests section

  • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)

Hey, I noticed you changed src/languages/en.ts in a PR from a fork. For security reasons, translations are not generated automatically for PRs from forks.

If you want to automatically generate translations for other locales, an Expensify employee will have to:

1. Look at the code and make sure there are no malicious changes.
2. Run the Generate static translations GitHub workflow. If you have write access and the K2 extension, you can simply click: [this button]

Alternatively, if you are an external contributor, you can run the translation script locally with your own OpenAI API key. To learn more, try running:

npx ts-node ./scripts/generateTranslations.ts --help

Typically, you'd want to translate only what you changed by running npx ts-node ./scripts/generateTranslations.ts --compare-ref main

🤖 No help site changes required.

I reviewed the changes in this PR against Expensify's help site files under App/docs/articles and don't believe any updates are needed.

Why: This PR is a permission/error-handling refinement in the Workflows bank account flow. Instead of routing a non-workspace-admin (e.g. a payments admin) to the admin-only workspace currency page when the workspace has an unsupported output currency, it now shows a "Not so fast" confirmation modal explaining they should contact a workspace admin. Workspace admins retain the existing "Update workspace currency" behavior. The change is limited to WorkspaceWorkflowsPage.tsx plus the new notAllowedToAddBankAccount copy string across the language files.

I checked the articles that document these flows and none describe this edge case in a way that becomes inaccurate:

• Workspace Workflows — documents enabling Payments and connecting a business bank account, but not the unsupported-currency permission modal.
• Connect a Business Bank Account
• Global Reimbursement – Add a Deposit Account

None of these get into which role can change the workspace currency from within the add-bank-account flow, so the new modal doesn't contradict or require new documentation. This is an in-app guardrail rather than a documented product capability.

⚠️ Note: I could not verify this in the browser (NewDot web could not be driven in this run), so this conclusion is based on static analysis of the diff and the help site markdown only.

@ShridharGoel, if you feel this behavior should be documented (for example, in the Workspace Workflows article), let me know and I'll draft the help site PR.
