Refactor WeeklyFinancialReportRepository to Preserve Group Order

- Removed alphabetical sorting of high, medium, and low marginality groups in the `WeeklyFinancialReportRepository`.
- Added a comment to clarify the intention of preserving the established order in the group data.

This change enhances the report's clarity by maintaining the original grouping order, improving the overall organization of financial data.
