fix(firestore): restore generic root type exports

[russellwheatley]

Description

Fix a Firestore TypeScript regression where root imports like DocumentSnapshot, Transaction, and WriteBatch resolved to non-generic runtime class declarations instead of the intended public generic types.

This updates the Firestore root export surface and emitted declarations so root-imported Firestore types behave correctly in type positions again, and adds regression coverage for the reported usage patterns.

Why compare-types did not catch it

compare-types currently compares Firestore modular/type files such as types/firestore.d.ts and modular.d.ts, not the package root index.d.ts consumer surface.

Because the generic types already existed in the modular/type declarations, the script saw the Firestore shapes as matching. The regression was in how the root package entrypoint re-exported those symbols for consumers importing from @react-native-firebase/firestore, which sits outside the current compare-types boundary.

Code Review

This pull request introduces generic type support (AppModelType and DbModelType) across the Firestore SDK, including CollectionReference, DocumentReference, DocumentSnapshot, Query, QuerySnapshot, Transaction, and WriteBatch. These changes enable improved type safety when working with custom data models and converters. The review feedback identifies opportunities to simplify type casting in FirestoreTransaction.ts where existing type information makes double-casting redundant.
