Enhanced date range parsing with more flexible input formats

- Added support for 'this week' and 'this month' date ranges
- Added support for month names (e.g., 'february', 'july') with automatic year detection
- Added support for 'month year' format (e.g., 'july 2023', 'feb 2022')
- Enhanced help text and examples for all report commands
- Added comprehensive test coverage for date range parsing
- Fixed timezone handling in TUI history display
- Minor code style improvements
