Code Review
This pull request restructures the demo application by modularizing the Auth demos and introducing new demonstration activities for Firebase Realtime Database, Firestore, and Storage (using Glide). It also updates FirestorePagingSource to properly handle InterruptedException and avoid undeliverable RxJava exceptions. Feedback focuses on several key improvements: configuring and initializing the Realtime Database emulator, exposing and passing the emulator mode to the Auth chooser screen, resolving a bug in the Storage demo where Glide loads are triggered on every keystroke, programmatically converting dp to pixels for view holder padding to avoid raw pixel anti-patterns, and optimizing Firestore data seeding using a WriteBatch.

A few suggestions and nits on the demo additions below.
This branch also carries an unrelated commit (d382bd5, the sign-up display name validation fix) that doesn't belong here, likely from being stacked on another branch. Worth rebasing it out before merge, same ask as on the edge-to-edge insets PR.

This runs on every onCreate(), including activity recreation (e.g. rotation), but useEmulator() can only be called once per FirebaseFirestore/FirebaseDatabase instance before first use, so a second call throws IllegalStateException. Worth guarding this with a one-time flag or moving it to Application.onCreate().

Same issue here for the Database emulator call.

This import landed mid-block instead of alphabetically. Minor, but worth fixing if there's a lint/spotless pass anyway.

Same unsorted import here.

This uses the fully-qualified activity name while the other moved auth activities (e.g. .auth.CredentialLinkingDemoActivity below) use the shorter relative style. Worth picking one convention for consistency.
