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. 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.

Checklist

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

@F3n67u openapi-fetch is entering maintenance mode, and is unlikely to accept this change, particularly as it introduces new, non-optional behavior around payload / type validity.
