fix(frontend): simplify marketplace version history to clean list

Replace card-based version display with simple list format:
- Single line per version: version number + current badge + description
- Current version highlighted in blue text
- No borders or background styling on items
- Clean, scannable layout with minimal visual noise
- Fixed TypeScript issues with proper data type checking

This provides the same information in a much cleaner, less
overwhelming format that's easier to read at a glance.
