Refactor entities and codebase for native property usage

- Replaced getters/setters with direct property access across entities and repositories.
- Added and configured `martin-georgiev/postgresql-for-doctrine` for PostgreSQL enhancements.
- Updated Doctrine configuration with types, mappings, and JSONB query functions.
- Removed unused `EliminationService` and related YAML configurations.
