Use Android App link for redirect URI

[hamorillo]

Description

This PR migrates from the custom schema used for the OAuth redirection to use Android App Link.

The behaviour in the login flow should be identical from the users' point of view.

All the backend configuration is already done, so it should work smoothly.

Note: Don't forget to update your project secrets.

Testing Steps

❗ Test both debug and prototype build as we need to verify that both fingerprints are correct in the backend.

• Verify that the app works as expected after the login (OAuth) flow. Sign out and sign in.
• [Use Prototype Build] Verify that the app works as expected after the login (OAuth) flow. Sign out and sign in.
