Refactor: rename BottomNavigation and update TendersScreen structure

- Renamed BottomNavigation to TenderBottomNavigation for clarity.
- Updated TendersScreen to use TenderBottomNavigation.
- Converted TendersScreen from StatelessWidget to StatefulWidget to manage tab state.
- Added TabController for handling tab changes and improved layout with SafeArea and PageView.
