ci: update workflow for SDK 36; refactor JaCoCo coverage configuration

Update the GitHub Actions workflow to install Android SDK 36 packages and transition to module-specific Gradle tasks for testing and reporting. Refactor the JaCoCo task in the app module to correctly identify Kotlin and Java class directories and target specific execution data paths.

Additional changes include:
- Add funding configuration via Ko-fi
- Update CI to use `:app:` namespaced Gradle tasks for unit tests and coverage
- Optimize JaCoCo task dependencies by removing redundant coverage report tasks
