Simplify test setup and reorganize test structure

Test organization:
- Split tests into unit/ and integration/ folders
- Unit tests (test_attribute_type, test_hash, test_settings) run without Docker
- Integration tests require MySQL and MinIO services
- Update imports to use absolute paths (from tests.schema import ...)

Configuration simplification:
- Change pytest_env defaults to localhost (was Docker hostnames)
- Simplify pixi tasks (env vars now use defaults)
- Update devcontainer to set Docker-specific env vars
- Update docker-compose comments

Tests now run with just:
  pip install -e ".[test]"
  docker compose up -d db minio
  pytest tests/

Unit tests only:
  pytest tests/unit/

Bump version to 2.0.0a5
