Update CI configuration and add optimizations

- Add test stage to GitLab CI with Flutter analyze and test commands
- Add memory optimization flags for builds (split-debug-info, obfuscate)
- Add pub-cache caching to improve build times
- Fix broken tests by removing old torrent service tests and adding simple working test
- Add missing Flutter imports to fix test compilation errors
- Configure CI to run tests and builds efficiently while minimizing RAM usage
