feat: expand test coverage and configure comprehensive alerting

- Add unit tests for all core services (identity, intake, finance, dataroom)
- Create integration test framework with shared setup utilities
- Add E2E test suite for complete user workflows
- Add test utilities package (server factory)
- Configure Prometheus alert rules (service health, infrastructure, database, Azure)
- Add alert rules ConfigMap for Kubernetes
- Update Prometheus deployment with alert rules
- Fix tsconfig.json to include test files
- Add tests/tsconfig.json for integration/E2E tests
- Fix server-factory.ts linting issues

+
+## Running Tests
+
+### All Tests
+```bash
+pnpm test
+```
+
+### Unit Tests Only
+```bash
+pnpm test -- --run unit
+```
+
+### Integration Tests
+```bash
+pnpm test -- --run integration
+```
+
+### E2E Tests
+```bash
+pnpm test -- --run e2e
+```
+
+### With Coverage
+```bash
+pnpm test -- --coverage
+```
+
+## Test Coverage Goals
+
+- **Target**: 80%+ coverage across all services
+- **Current**: Expanding coverage
+- **Priority**: Critical service paths first
+
+## Test Types
+
+### Unit Tests
+- Service-specific tests in `services/*/tests/`
+- Test individual functions and modules
+- Mock external dependencies
+
+### Integration Tests
+- Test service interactions
+- Use test database
+- Test API endpoints
+
+### E2E Tests
+- Test complete user workflows
+- Test across multiple services
+- Test real-world scenarios
+
+## Test Utilities
+
+### Test Context
+- `setupTestContext()` - Initialize all services
+- `teardownTestContext()` - Clean up services
+- `cleanupDatabase()` - Clean test data
+
+### Fixtures
+- Test data factories
+- Mock services
+- Test helpers
+
+## Best Practices
+
+1. **Isolation**: Each test should be independent
+2. **Cleanup**: Always clean up test data
+3. **Mocking**: Mock external services
+4. **Coverage**: Aim for 80%+ coverage
+5. **Speed**: Keep tests fast
