refactor: move core/infrastructure/ to infrastructure/, fix layer violations

- Move app_config, health, statistics, geoip from core/infrastructure/ to
  infrastructure/ — completes hexagonal layer separation
- Rename MLService to AppServices (name reflected actual contents: health,
  statistics, ML engine, not just ML)
- Fix core/ → adapter/ dependency violations: jwt.rs, email/scheduler.rs,
  email/report.rs now use dyn RepositoryPort trait instead of concrete Database
- Move misplaced data types to model/:
  - Claims → model/auth.rs
  - AlertMessage → model/ml_detection.rs
  - LicensePayload + LicenseInfo → model/license.rs
  - DropEventMessage + DropCounters → model/drop_event.rs
  - InferenceConfig (ML JSON) → model/config.rs as MLInferenceConfig
- Wire CommunicationManager: enforce mode flow now goes through CQRS
  (ChangeEnforceModeCommand + GetEnforceModeQuery via EnforceModeHandler)
- Add GitHub Actions CI workflow (cargo check + test + clippy)
- Add 9 new tests (38 total): enforce mode handler (3), auth validation (6)
- core/ now contains only business logic with no adapter imports
  (except #[cfg(test)] blocks which need concrete types)
