WEB-573: refactor password preferences UI to card-based layout

- Convert horizontal radio layout to vertical card-based blocks
- Add heading labels (Basic, Standard, Strong) for each policy option
- Position radio buttons and headings on same row with space-between
- Increase padding and spacing for improved visual clarity
- Maintain full-width blocks with consistent vertical stacking
- Preserve all existing text content and functionality
- Add trackBy function to *ngFor for performance optimization
- Use translation keys for password labels instead of hardcoded array
- Map labels based on preference ID for robustness
