Tests E2E de flujo wallet (onboarding -> deposit)

[Kalebtron1]

Why this matters

Automated E2E coverage protects the wallet flow against regressions.

Problem

The onboarding and deposit flow does not have a repeatable E2E safety net.

Scope

• Add or extend the E2E path for onboarding, wallet setup, and deposit.
• Keep the test data deterministic and easy to reset.
• Document any mocks or fixtures needed for the flow.

Implementation guidance

• Use playwright.config.ts, playwright-fixture.ts, src/components/DepositModal.tsx, src/pages/Onboarding.tsx, and src/components/WalletSetupModal.tsx as the main touch points.
• Add the test next to the current Playwright or fixture setup.
• Keep the test focused on the most important user journey.

Out of scope

• A full test suite for every app route.
• Adding flaky dependencies that make the test hard to run.

Acceptance criteria

• PR includes the automated test and the instructions to run it.
• Reviewer can execute the documented command and see the expected pass result.
• The PR description states which user journey is protected by the test.

Validation

• Run the documented Playwright or E2E command locally.
• Run npm run build if the test change touches app code.
• Confirm the flow passes from onboarding through deposit.

PR requirements

• Include Closes #49.
• Document how to run the test locally.
• Explain what user journey is covered and what is not.

Complexity

• Medium (100 points)
