fix: hide project descriptions in short CV view

Change project ShortDescription from 'short-desc' to 'long-only' class.
Project descriptions now only appear in expanded long CV view, keeping
the projects section more concise by default.

Projects now show:
- Title and date (always visible)
- Description (long view only)
- Responsibilities (long view only)
- Technologies (long view only)
