test: Add comprehensive test coverage for untested modules
Add tests for previously untested components and services: - apiKeyService.ts: localStorage operations (14 tests) - ApiKeyModal.tsx: form validation, submission (22 tests) - App.tsx: state transitions, error handling (23 tests) - latexService.ts: API calls, template detection (35 tests) - latex_service.py: LaTeX escaping, compilation (59 tests) - server.py: Flask routes, field mapping (38 tests) Also fix geminiService tests by adding proper apiKeyService mock. Total new test coverage: 173 TypeScript tests, 97 Python tests https://claude.ai/code/session_01D4k6b4nUjwfcHMvectsri2
