feat(project-view): add user permission-based tab filtering

- Implemented a new function to filter project view tabs based on user finance permissions, enhancing the user experience by conditionally displaying the finance tab.
- Updated the project view component to utilize the new filtering function, ensuring that only authorized users can access finance-related features.
- Refactored URL parameter handling to accommodate the filtered tab items, improving state management and user navigation.
