feat: Implement integration testing

[Mansi-mParticle]

Background

• This PR introduces an automated end-to-end integration testing framework for the Android SDK, aligned with the existing iOS setup.
  It uses WireMock to validate SDK network requests against expected baselines and runs automatically in CI.
  This improves regression detection and increases confidence when shipping changes to the SDK.

What Has Changed

• This PR adds a Android test app and a suite of automated scripts to run end-to-end integration tests with WireMock. The framework captures SDK network requests, normalizes dynamic fields, and validates them against stored baselines.Scripts handle WireMock and emulator management, app building, test execution, recording, and verification.Key features include zero-configuration startup, secure credential handling, baseline comparison, cross-platform support, and robust error reporting.
