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.

+## Testing Strategy
+
+The project uses a three-tier testing approach:
+
+### Test Categories
+
+1. **Unit Tests** (`apps/api/tests/unit/`)
+   - Fast tests with no external dependencies
+   - Use SQLite in-memory database
+   - Run with: `make test-unit` or `pytest -m unit`
+
+2. **Integration Tests** (`apps/api/tests/integration/`)
+   - Test API endpoints with database
+   - Use PostgreSQL with transaction rollback
+   - Run with: `make test-integration` or `pytest -m integration`
+
+3. **System/E2E Tests** (`e2e/`)
+   - End-to-end tests using Playwright
+   - Test full user journeys
+   - Run with: `make test-e2e`
+
+### Running Tests
+
+```bash
+# Run all tests (excludes system tests by default)
+make test
+
+# Run specific categories
+make test-unit          # Fast unit tests only
+make test-integration   # Integration tests with DB
+make test-system        # Full stack tests
+make test-e2e          # Browser-based E2E tests
+
+# Inside Docker container
+docker compose exec api pytest -v -m unit
+docker compose exec api pytest -v -m integration
+```
+
+### Test Markers
+
+Tests are marked with pytest markers:
+- `@pytest.mark.unit` - Fast, isolated tests
+- `@pytest.mark.integration` - Tests with database/external services
+- `@pytest.mark.system` - Full stack tests
+
+### Shared Fixtures
+
+Common fixtures are in `apps/api/tests/conftest.py`:
+- `sqlite_engine` - SQLite engine for unit tests
+- `postgres_engine` - PostgreSQL engine for integration tests
+- `db_session` - Database session with transaction rollback
+- `test_client` - FastAPI TestClient instance

+## Context
+
+Current test infrastructure has ~50 backend tests and 12 frontend tests. Backend tests are mixed in a single directory with inconsistent patterns. Some tests require a running PostgreSQL instance even when testing pure logic. There's no E2E test coverage.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Separate tests into unit/integration/system categories with clear boundaries.
+- Create shared fixtures to eliminate duplication.
+- Enable fast unit tests without PostgreSQL (SQLite in-memory).
+- Implement proper transaction isolation for integration tests.
+- Add E2E tests for critical user journeys (login, project creation).
+- Make tests runnable both locally and in Docker.
+
+**Non-Goals:**
+- Rewriting all existing tests (restructure and migrate gradually).
+- Adding tests for features that don't exist yet.
+- Complex test parallelization setup.
+- Performance benchmarking.
+
+## Decisions
+
+1. **Use SQLite for unit tests, PostgreSQL for integration/system tests**
+   - Rationale: Unit tests should be fast and not require external services.
+   - SQLite runs in-memory, no Docker needed.
+
+2. **Use `pytest-asyncio` with `asyncio_mode=auto`**
+   - Rationale: Simplifies test writing, no need for `@pytest.mark.asyncio` on every test.
+
+3. **Shared `conftest.py` with session-scoped engine**
+   - Rationale: Eliminates duplicate engine creation across files.
+   - Integration tests use `begin_nested()` for transaction rollback.
+
+4. **Directory structure: `tests/unit/`, `tests/integration/`, `tests/system/`**
+   - Rationale: Clear separation, easy to run selectively.
+   - `pytest -m unit` runs all unit tests regardless of location.
+
+5. **Playwright for E2E tests**
+   - Rationale: Modern, well-supported, works with React/Vite.
+   - Tests run against the actual deployed application.
+
+## Risks / Trade-offs
+
+- **[SQLite vs PostgreSQL behavior differences]** -> Document known differences (e.g., JSON operators, asyncpg-specific features).
+- **[Migration effort for existing tests]** -> Migrate gradually, prioritize new tests over rewriting old ones.
+- **[E2E tests are slower]** -> Run them selectively (not on every commit), maybe only in CI or nightly.
+
+## Migration Plan
+
+1. Create new directory structure.
+2. Implement shared fixtures in `conftest.py`.
+3. Add SQLite support for unit tests.
+4. Migrate 2-3 existing tests as examples.
+5. Add Playwright setup and 1-2 E2E tests.
+6. Update Makefile targets.
+7. Document testing strategy.
+
+## Open Questions
+
+- Should we use `pytest-xdist` for parallel test execution?
+- Should E2E tests run against the Docker compose setup or a staging environment?

+## Why
+
+The current test infrastructure has several issues that slow development and reduce confidence:
+
+1. **Mixed test types in single directory**: Unit, integration, and system tests are all mixed together in `apps/api/tests/`, making it hard to run fast unit tests independently.
+2. **Duplicate fixture code**: Database setup/teardown is duplicated across multiple test files instead of using a shared `conftest.py`.
+3. **Inconsistent test patterns**: 4 different patterns exist for database setup (sync helpers, async fixtures, module reloads, autouse env vars).
+4. **No test database isolation**: Tests truncate tables manually instead of using transaction rollback, leading to potential data leakage.
+5. **Backend tests require live PostgreSQL**: Unit tests that test pure logic still connect to a real database.
+6. **No E2E/system tests**: There's no automated way to test the full stack (frontend + API + database) together.
+7. **Import errors in local environment**: Tests depend on packages not in `dev` dependencies (e.g., `python-jose`).
+
+## What Changes
+
+- **Restructure backend tests** into `unit/`, `integration/`, and `system/` directories.
+- **Create shared fixtures** in `conftest.py` for database sessions, test client, and authentication.
+- **Add SQLite in-memory support** for fast unit tests that don't need PostgreSQL.
+- **Implement transaction rollback isolation** using `begin_nested()` for integration tests.
+- **Add missing test dependencies** to `pyproject.toml`.
+- **Create E2E test setup** using Playwright for critical user journeys.
+- **Add test markers** (`@pytest.mark.unit`, `@pytest.mark.integration`, `@pytest.mark.system`) to enable selective test runs.
+- **Update Makefile** with `test-unit`, `test-integration`, `test-system`, and `test-e2e` targets.
+
+## Capabilities
+
+### New Capabilities
+- `test-organization`: Structured test directories with clear separation of concerns.
+- `test-isolation`: Transaction rollback and SQLite support for fast, isolated tests.
+- `e2e-testing`: Playwright-based end-to-end tests for critical user journeys.
+
+### Modified Capabilities
+- `docker-infrastructure`: Add test database service and test runner configuration.
+
+## Impact
+
+- `apps/api/tests/`: Restructured into subdirectories.
+- `apps/api/pyproject.toml`: New test dependencies added.
+- `apps/api/conftest.py`: New shared fixtures file.
+- `Makefile`: New test targets.
+- New `e2e/` directory for Playwright tests.
+- CI pipeline may need updates to run new test categories.
