fix(typescript): make auth mocks reusable and fix offset pagination wire tests

[devin-ai-integration]

Description

Fixes wire test generation for paginated endpoints with OAuth/inferred auth, and for offset pagination with step but no hasNextPage property.

Refs https://github.com/fern-demo/hiddenlayer-ts-sdk/actions/runs/26247548581/job/77249728300

Changes Made

1. Auth mock endpoints are now reusable ({ once: false })

Both OAuth client credentials and inferred auth mock generation in TestGenerator.ts previously used .mockEndpoint() (single-use). When a paginated endpoint calls getNextPage(), it triggers a second HTTP request which needs re-authentication. The single-use mock was already consumed, causing ECONNREFUSED on localhost:80.

Changed both mock auth generation paths (lines ~471 and ~537) to use .mockEndpoint({ once: false }).

2. Offset pagination with step skips getNextPage assertions

For offset pagination without an explicit hasNextPage response property but WITH a step (limit) property, the SDK's hasNextPage() check uses items.length >= step. Mock data may not satisfy this condition (e.g., 2 items with limit=10), causing hasNextPage() to return false when the test asserts true.

When step is defined but hasNextPage is not, isPaginationCursorMissingInExample now returns true, correctly skipping the getNextPage() assertions. When neither step nor hasNextPage is defined, the SDK uses items.length > 0 which works with any non-empty mock data, so assertions are still generated.

• Updated seed test snapshots for all affected fixtures (pagination, oauth, inferred-auth, any-auth, etc.)

Testing

• pnpm seed test --generator ts-sdk --fixture pagination — 2/2 passed
• pnpm seed test --generator ts-sdk --fixture oauth-client-credentials — 2/2 passed
• pnpm seed test --generator ts-sdk --fixture oauth-client-credentials-default — 1/1 passed
• pnpm seed test --generator ts-sdk --fixture inferred-auth-explicit — 1/1 passed
• pnpm seed test --generator ts-sdk --fixture inferred-auth-implicit — 1/1 passed
• pnpm seed test --generator ts-sdk --fixture any-auth — 3/3 passed
• All other affected fixtures verified (endpoint-security-auth, websocket-inferred-auth, etc.)
• Pre-existing expected failures remain expected (oauth-client-credentials-custom, inferred-auth-implicit-reference)

SDK Generation Benchmark Results

Comparing PR branch against median of 5 nightly run(s) on main (latest: 2026-05-21T05:23:53Z).

Generator	Spec	main (generator)	main (E2E)	PR (generator)	Delta
ts-sdk	square	231s (n=5)	240s (n=5)	221s	-10s (-4.3%)

main (generator): generator-only time via --skip-scripts (includes Docker image build, container startup, IR parsing, and code generation — this is the same Docker-based flow customers use via fern generate). main (E2E): full customer-observable time including build/test scripts (nightly baseline, informational). Delta is computed against generator-only baseline.
⚠️ = generation exited with a non-zero exit code (timing may not reflect a successful run).
Baseline from nightly runs on main (latest: 2026-05-21T05:23:53Z). Trigger benchmark-baseline to refresh.
