fix(data): standardize month formatting to two digits
Updated the month keys in the `finances.json` file to use a two-digit format. Adjusted the `get_transparency_data` function to accommodate this change by zero-padding single-digit months. This ensures consistency in data representation and prevents potential errors in handling financial data.
