Pull request overview

This PR upgrades the Android/Gradle toolchain (Gradle/AGP/Kotlin/Java), migrates tests away from deprecated PowerMock/old Mockito matchers toward modern Mockito APIs, and updates CI/docs accordingly.

Changes:

• Upgrade build tooling to Gradle 8.x / AGP 8.x / Kotlin 2.0.x and move compilation to Java 17.
• Update Android manifests/build scripts for AGP 8 namespace requirements and modern DSL (lint/jacoco).
• Refactor and update unit tests and GitHub Actions workflows to align with the new toolchain.
