feat: migrate to futbol-libre.su with resilient domain architecture

- Add SiteConfig: centralized domain management with dynamic resolution
- Fix stream extraction: pattern-based URL detection instead of hardcoded host check
- decodeEmbeddedEventUrl now detects eventos URLs by structure (path + param), not domain
- StreamRepository and StreamOptionMetadata use SiteConfig as single source of truth
- Domain auto-discovery: probes known domains on app start, persists working one
- Update network_security_config with new domain + CDN
- Add unit test infrastructure (JUnit, MockK, Truth) with 24 tests
- Improve error handling in MainFragment with descriptive messages
