fix: Resolve works filter display and encoding issues

Problem 1: Only 3 works visible despite 8/10 badge
- Added max-height: 300px and overflow-y: auto to .works-list
- Now all 10 works are scrollable in the filter section

Problem 2: UnicodeEncodeError with → character in console
- Replaced Unicode arrow (→) with ASCII arrow (->) in print statements
- Fixes 'charmap' codec error on Windows console
