442716d9c0 fix: Correct completeness check to use last working day instead of fixed 31.12
- Fixed is_yearly_data_complete() to check for last working day of year instead of fixed 31.12
- Added get_last_working_day_of_year() function to determine actual last working day
- For 2023: Last working day is 29.12.2023 (Friday), not 31.12.2023 (Sunday)
- For 2024: Last working day is 31.12.2024 (Tuesday), same as fixed date
- Respects weekends and holidays when determining last working day
- Prevents unnecessary re-downloads of complete yearly data files
- Maintains backward compatibility with existing functionality
- Improves efficiency by avoiding redundant downloads of multi-megabyte files
- Added proper debug output for completeness checking
- Updated all modules to use consistent debug printing

9c7e1f8302 fix: Implement correct tax methodology for yearly average calculation
- Fixed calculation to use proper GFŘ methodology for tax purposes
- Now calculates arithmetic average of rates at last day of each month
- Corrects 2023 USD to 22.138 (was 22.210, expected 22.140)
- Corrects 2024 USD to 23.283 (was 23.208, expected 23.280)
- Added detailed debug output showing monthly breakdown
- Maintains all other statistical calculations (quarterly, monthly averages)
- Clearly distinguishes tax yearly average from regular working day average
- Uses get_valid_last_day_of_month() to find last business day of month
- Shows both tax average and regular working day average in output
- Fully compliant with § 38 zákona o daních z příjmů methodology
