feat: add kover for code coverage

This commit adds kover to the project for code coverage analysis and integrates it with the CI workflow.

- Adds
 kover dependency and configuration for Android modules.
- Includes a step to generate kover XML reports in the build workflow.
- Utilizes the madrapps/jacoco-report action to display test coverage and enforce minimum coverage thresholds.
- Adjusts the build trigger to run on pull requests instead of pushes
 to the develop branch.
- Reduces the build timeout to 30 minutes.
