feat(filters): enhance labels and members filter dropdowns

- Added useEffect to fetch labels when the component mounts or projectId changes in LabelsFilterDropdown.
- Improved members filter logic to only sync board members when the board task assignees are empty.
- Cleaned up redundant checks and optimized dependencies in the members filter dropdown.
