feat(admin-center): implement admin center settings retrieval and enhance holiday population logic

- Added a new API endpoint in AdminCenterController to fetch admin center settings, including organization details.
- Updated the admin center API router to include the new settings route.
- Enhanced the holiday controller to check for recent holiday population before attempting to repopulate, preventing duplicate entries.
- Improved the holiday calendar component to manage holiday population attempts and display loading states.
- Updated localization files to support new messages related to calculation methods and holiday settings.
