test: verify self-onboarding email requirement (v2026-02-01)

[jeffredodd]

Summary

⚠️ Sub-PR off #2233 (the v2026-02-01 base bump).

v2026-02-01 makes email a server-required field on self-onboarding employee-create. The SDK's Zod schema already enforces this client-side (buildFormSchema.test.ts:382-412), so the bump is verify-only at the SDK layer — no production code change.

Changes

• e2e/tests/employee/04-self-onboarding-email-required.spec.ts (new): drives the self-onboarding profile form without filling email and asserts the client-side validation surfaces before the request is sent.

Currently test.skip pending a scenario that provisions a fresh self-onboarding employee from scratch. The assertion shape is in place so the implementation has a target.

What we expect post-upgrade

• buildFormSchema.test.ts continues to enforce email-required on self-onboarding submit.
• Existing 92-self-onboarding-submit.spec.ts continues to pass against Demo.
• New 04-self-onboarding-email-required.spec.ts proves the new contract via the negative case.

Test plan

• buildFormSchema.test.ts green after the base PR's dep bump
• 92-self-onboarding-submit.spec.ts still green against Demo
• Stage a fresh-self-onboarding scenario and un-skip 04-self-onboarding-email-required.spec.ts

Superseded by the base PR #2233 — the E2E scaffold for this breaking change was moved onto the base branch so the upgrade-base CI shows the verification trail directly (per Jeff's review-flow ask). This sub-PR's diff is now empty and can be closed; no further SDK code change was needed for this breaking change.
