fix(openapi-fetch): reject excess request body and params properties

[F3n67u]

Changes

Fixes #1769 in openapi-fetch.

This changes openapi-fetch's request typing so excess properties are rejected consistently for body and params, while preserving parseAs inference. It also moves the new regression coverage into dedicated *.test-d.ts type tests and adds the missing query array params to the shared common.yaml fixture used by params tests.

How to Review

Review packages/openapi-fetch/src/index.d.ts first to verify the parseAs typing now flows through a dedicated generic instead of the full inferred Init object.

Then review the new type tests:

• packages/openapi-fetch/test/http-methods/post.test-d.ts
• packages/openapi-fetch/test/http-methods/request.test-d.ts
• packages/openapi-fetch/test/path-based-client/path-based-client.test-d.ts
• packages/openapi-fetch/test/common/params.test-d.ts

Checklist

• Unit tests updated
• docs/ updated (not needed)
• pnpm run update:examples run (not applicable)
