feat(project-currency): implement project-specific currency support

- Added a currency column to the projects table to allow different projects to use different currencies.
- Updated existing projects to default to 'USD' if no currency is set.
- Enhanced project finance controller to handle currency retrieval and updates.
- Introduced API endpoints for updating project currency with validation.
- Updated frontend components to display and manage project currency effectively.
