test(objectql): drop two as any erasures on ordinary engine reads (#4918 ratchet)

`check:query-options-erasure` reported the test surface growing 267 -> 269: the
#5503 test file passed `{ where: { id } } as any` to `findOne` and `{} as any`
to `find`. Neither is deliberately off-contract — both values are plain
`EngineQueryOptions` that the signatures already infer — so the gate's FIRST
remedy applies (drop the assertion), not the `as unknown as EngineQueryOptions`
spelling reserved for tests whose subject IS off-contract input.

The baseline is untouched: the count returns to its 267 ceiling on its own.
