feat(projects): enhance project selection and grouping functionality

- Added grouping options for projects by category, team, and status in the project list.
- Implemented search functionality with a clear search option.
- Improved UI with expandable/collapsible project groups and selection summary.
- Updated localization files for English, Spanish, and Portuguese to include new grouping and UI strings.
- Enhanced project type definitions to support additional grouping properties.
