feat(task-breakdown-api): implement task financial breakdown API and related enhancements

- Added a new API endpoint `GET /api/project-finance/task/:id/breakdown` to retrieve detailed financial breakdown for individual tasks, including labor hours and costs grouped by job roles.
- Introduced a new SQL migration to add a `fixed_cost` column to the tasks table for improved financial calculations.
- Updated the project finance controller to handle task breakdown logic, including calculations for estimated and actual costs.
- Enhanced frontend components to integrate the new task breakdown API, providing real-time financial data in the finance drawer.
- Updated localization files to reflect changes in financial terminology across English, Spanish, and Portuguese.
- Implemented Redux state management for selected tasks in the finance drawer.
