intergration testing

[mofex99]

Create a comprehensive test that simulates the full workflow:

• Mock the Google Speech-to-Text API to return a fake transcript.
• Mock the Gemini API (LLM) to return structured task data from the transcript.
• Simulate a POST request to the /api/transcribe endpoint (if needed).
• Simulate a POST request to /api/save_task with the mocked Gemini output.
• Verify that the task is successfully saved to the database using get_all_tasks().

Goals:

• Validate that the full transcription-to-task flow works end-to-end.
• Ensure test reliability by monkey patching external dependencies.
