Fusion 3ccd94f661 feat: restructure test infrastructure with unit/integration/system separation
Test Organization:
- Create tests/unit/, tests/integration/, tests/system/ directories
- Move existing tests into appropriate categories
- Add pytest markers (@pytest.mark.unit, @pytest.mark.integration)

Shared Fixtures:
- Create conftest.py with SQLite engine (for unit tests)
- Add PostgreSQL session fixture with transaction rollback
- Add TestClient fixture for API tests

Configuration:
- Update pyproject.toml with asyncio_mode=auto
- Add test markers and default addopts
- Add aiosqlite dependency for SQLite support

E2E Testing:
- Initialize Playwright in e2e/ directory
- Add playwright.config.ts
- Create login flow E2E test

Build:
- Add test-unit, test-integration, test-system, test-e2e to Makefile
- Update test target to run all categories
- Add testing documentation to README

Note: Some tests have import issues due to missing python-jose
package in dev environment. This needs to be addressed separately.

## ADDED Requirements
### Requirement: Shared Test Fixtures
The system SHALL provide shared fixtures in `conftest.py` for common test needs.
#### Scenario: Database session fixture
- GIVEN an integration test
- WHEN using the `db_session` fixture
- THEN it SHALL provide an async SQLAlchemy session
- AND the session SHALL use transaction rollback for isolation
#### Scenario: Test client fixture
- GIVEN an API integration test
- WHEN using the `client` fixture
- THEN it SHALL provide an authenticated TestClient instance
- AND the client SHALL have valid access and refresh tokens
#### Scenario: SQLite unit test database
- GIVEN a unit test
- WHEN the test uses the `db_engine` fixture
- THEN it SHALL provide an in-memory SQLite engine
- AND no PostgreSQL connection SHALL be required
### Requirement: Transaction Isolation
The system SHALL ensure integration tests don't pollute the database.
#### Scenario: Rollback after test
- GIVEN an integration test creates data
- WHEN the test completes
- THEN all database changes SHALL be rolled back
- AND subsequent tests SHALL see a clean database state
#### Scenario: Parallel test safety
- GIVEN multiple integration tests run concurrently
- WHEN each test uses transaction isolation
- THEN tests SHALL not interfere with each other
