feat(project-finance): add billable filter functionality to project finance queries

- Introduced a `billable_filter` query parameter to filter tasks based on their billable status (billable, non-billable, or all).
- Updated the project finance controller to construct SQL queries with billable conditions based on the filter.
- Enhanced the frontend components to support billable filtering in project finance views and exports.
- Added corresponding translations for filter options in multiple languages.
- Refactored related API services to accommodate the new filtering logic.
