fix(android, firestore): detach snapshot listeners before executor shutdown

[christian-apollo]

Summary

Removes Firestore snapshot listeners before super.invalidate() in ReactNativeFirebaseFirestoreCollectionModule and ReactNativeFirebaseFirestoreDocumentModule.

ReactNativeFirebaseModule.invalidate() shuts down TaskExecutorService; sendOnSnapshotEvent uses Tasks.call(getTransactionalExecutor(...), ...). If the executor is terminated first, a late snapshot can throw RejectedExecutionException (terminated pool).

This matches the teardown order already used in ReactNativeFirebaseFirestoreTransactionModule.

Test plan

• Android: enable Firestore onSnapshot, trigger RN reload or scenario that invalidates native modules; confirm no crash (manual / existing e2e if any)

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a potential crash in Android when React Native modules are invalidated. By adjusting the order of operations during module teardown, it ensures that Firestore snapshot listeners are properly unregistered before the underlying executor service is shut down, thereby preventing runtime exceptions and improving application stability.

Highlights

• Firestore Snapshot Listener Teardown: Reordered the invalidation process in ReactNativeFirebaseFirestoreCollectionModule and ReactNativeFirebaseFirestoreDocumentModule to ensure Firestore snapshot listeners are detached before super.invalidate() is called, preventing RejectedExecutionException during module shutdown.

Code Review

This pull request refactors the invalidate method in ReactNativeFirebaseFirestoreCollectionModule and ReactNativeFirebaseFirestoreDocumentModule. The super.invalidate() call is moved to the end of the method to ensure that module-specific listener cleanup and collection clearing occur before the superclass's invalidation logic. The review comments suggest an improvement to iterate SparseArrays using valueAt(i) for better readability and slightly improved performance.

Hey @christian-apollo 👋 - thanks for this - could you follow the link in either the comment or the CI check to read+accept the CLA? Happy to collaborate and merge but we have to have the CLA signed to take in code, thanks!

Looks like a nice fix

I'm okay with ignoring the suggested readability/performance optimizations from LLM review as I do not believe this will execute very frequently at all nor do I think the set of listeners will ever be large, it just doesn't seem consequential

waiting on CLA approval
