fix(coverage): enable JaCoCo coverage for Robolectric/Compose tests

- Upgrade JaCoCo from 0.8.12 to 0.8.14 (includes Compose bytecode filtering)
- Add includeNoLocationClasses=true for Robolectric test coverage
- Add jdk.internal.* exclusion for Java 9+ compatibility
- Use ASM-transformed classes for coverage report

This fixes the issue where Compose UI tests showed 0% coverage despite
passing tests. The combination of JaCoCo 0.8.14 and includeNoLocationClasses
enables proper coverage tracking for Robolectric-based Compose tests.
