fix: SDK update for version 29.3.1

[ChiragAgg5k]

This PR contains updates to the SDK for version 29.3.1.

What's Changed

• Fixed: added ProjectAuthMethodId.Passkey, so project.updateAuthMethod can enable passkeys
• Fixed: added ProjectPolicyId.Passkey and the Models.PolicyPasskey model, so getPolicy and listPolicies return the passkey policy

Completes the passkeys release: 29.3.0 shipped the passkey methods, but not the passkey auth method and policy IDs or the PolicyPasskey model, so the SDK could not enable passkeys on a project. Made from a spec with exactly these pieces removed, three-way merged onto 29.x. Build and all 903 jest tests pass.

The passkey lookup test still targets the password-dictionary path, leaving a minor coverage gap to fix.

This updates the SDK version to 29.3.1 and adds the passkey auth-method and policy identifiers. It also adds the passkey policy model to the policy response types and updates the changelog.

Fix with agent prompt

### Issue 1
test/services/project.test.js:1943-1944
**Test still exercises password-dictionary, not passkey**

This fixture has passkey fields, but the test still calls `getPolicy('password-dictionary')` and its `$id` remains `password-dictionary`. It will pass without ever exercising a passkey lookup, so it does not verify the newly added policy path.
