Replace game with soundtrack terminology and add fuzzy/exact search

- Replace all 'game' references with 'soundtrack' throughout frontend (112 occurrences)
- Add radio buttons for fuzzy/exact search in SearchModal
- Fuzzy search is default and uses /findfuzzy endpoint
- Exact search uses existing /find endpoint
- Fix syntax errors in SyncProgressModal from previous refactoring
