Mock db.is_configured in test_missing_uniqueid to isolate from environment

[Copilot]

The test_missing_uniqueid test was dependent on actual environment configuration (PGVECTOR_* vars), making it potentially flaky.

Changes

• Added @patch("api.db.is_configured", return_value=False) to test_missing_uniqueid
• Ensures test behavior is deterministic regardless of environment state
• Added .gitignore to prevent committing Python cache files and coverage reports

@patch("api.db.is_configured", return_value=False)
def test_missing_uniqueid(self, mock_db_configured, client, valid_wav_content):
    """Test that missing uniqueid is rejected when persistence is requested."""
    response = client.post(
        "/api/get_transcription",
        files={"file": ("test.wav", valid_wav_content, "audio/wav")},
        data={"persist": "true"},
    )
    
    assert response.status_code == 400
    assert "uniqueid" in response.json()["detail"]

The mock returns False to focus on uniqueid validation logic, which executes before the database configuration check in the API flow.
