Refactor logging setup across multiple modules to use loguru with consistent configuration

- Updated logging initialization in MessageCalendar, admin_edit_prof, elsa_main, graph, iconLine, searchPage, and richtext modules to use loguru.
- Changed log rotation and retention settings for log files to improve log management.
- Replaced logger.debug/info calls with log.debug/info for consistency.
- Fixed a typo in the searchPage UI and updated related references in the UI files.
- Removed unused imports and cleaned up code for better readability.
