feat: Enhance data structure and transparency features

- Moved `finances.json` and `services.json` to a new `data` directory for better organization.
- Introduced `get_latest_month` function in `helpers/finances.py` to dynamically determine the latest financial reporting period.
- Updated `main.py` to use the new data paths and implement dynamic generation of the transparency report date, improving the clarity of financial reports.
- Modified `membership.html` template to display financial report for the dynamically determined latest month, enhancing transparency for donations.

These changes aim to improve data management, make financial reporting more transparent, and ensure users have access to the most current financial information. Moving JSON files to a dedicated directory helps with organizing resources better. By dynamically determining the latest financial period, the application now avoids hard-coded dates, increasing accuracy and reducing maintenance effort.
