test(export-coverage): adds wallet-export coverage

[christopherferreira9]

Description

Adds end-to-end test coverage for wallet export (exportWallet = seed phrase, exportPrivateKey = private key), which previously had none. Coverage is layered across two levels that together verify the full path:

• Integration (headless, Vitest) — proves the SDK export functions succeed against the real backend/Turnkey and return well-formed encrypted bundles.
• Browser (Playwright) — drives the demo app's Export Keys UI and confirms the real decrypted secret actually renders in the Turnkey iframe.

Notes / trade-offs

• The browser test intentionally couples to Turnkey's remote iframe DOM (export.turnkey.com) to prove the secret is genuinely shown; a Turnkey UI change could break it independently of the
  SDK.
• Both suites self-skip when backend/email/demo-app are unavailable, matching the existing e2e specs.
• No wallet secret is ever written to logs (only shape summaries like word count).

New files

• e2e/integration/export-flow.test.ts
• e2e/helpers/test-wallet.ts - new — test bridge adapting the integration client+session into the ZeroDevWalletSDK shape the export functions expect (forces stamperType: 'apiKey', since parseSession omits it and the passkey stamper is a no-op), plus a throwaway target-public-key generator.
