types(queries): apply Mongoose casting to default MongoDB driver _id in RootFilterOperators

[vkarpov15]

Summary

Fix #15779
Fix #15887

MongoDB Node driver's RootFilterOperators uses Filter, which looks like this:

export declare type Filter<TSchema> = {
    [P in keyof WithId<TSchema>]?: Condition<WithId<TSchema>[P]>;
} & RootFilterOperators<WithId<TSchema>>;

WithId adds a default _id?: ObjectId, even for Record<string, any>. Without the change in this PR, that _id wouldn't get any Mongoose casting applied, which is what causes the issue in #15779 (comment)

Pull request overview

This PR fixes a TypeScript type inference issue where MongoDB's implicitly-added _id field wasn't receiving proper Mongoose casting in query filters. The change ensures that when using QueryFilter with types that don't explicitly define _id, the MongoDB driver's default _id?: ObjectId still gets Mongoose's query type casting applied (allowing both string and Types.ObjectId values).

Key Changes:

• Modified _QueryFilter type to use mongodb.WithId<T> for the RootFilterOperators parameter
• Added test case demonstrating the fix with aggregate queries using QueryFilter
