fix(openapi): use first user request example when response example name doesn't match

[devin-ai-integration]

Description

Refs: Slack thread from kenny

Fixes a bug where response-level examples in OpenAPI specs generated an extra example with requestBody: undefined. This caused response-level examples to produce 5 examples instead of 4 (matching schema-level examples).

Requested by: kenny

Changes Made

• Modified generateEndpointExample.ts to prioritize using the first user request example when a response example name doesn't match any request example name
• When using a non-matching response example, the display name now comes from the request example (not the response example)
• Updated test snapshots to reflect the fix (removes examples with requestBody: undefined)

Testing

• Unit tests pass
• Snapshot tests updated to verify both schema-level and response-level examples now generate the same number of examples (4) with correct names

Updates Since Last Revision

• Updated v3-importer-tests snapshots (examples-endpoint-level.json, examples-endpoint-level-named.json) to reflect the fix
• Merged with latest main

Review Checklist

• Verify the priority order change is correct: user request → auto request → base request
• Confirm that using the request example name as displayName (instead of response example name) is the desired behavior when there's no name match
• Review that marking firstUserRequestName as used in requestExamplesUsed doesn't cause unintended side effects in createExamplesForRemainingUserRequests
