Quick improvement for analytics reporting

Quick improvement on Analytics for posthog that would allow us to better filter reported decryption errors.

This is adding the following properties to all events: appVersion: similar to what web is doing. applicationId: the package id appFlavor: the flavor (googlePlay / FDroid) cryptoSDK: Parity with web, to allow to use common filters.

Also adding a specific property for E2E domain errors, that are not common to all platforms (is_cross_signed_verified).
