Fix script card click issues and missing Install button

- Fix type signature mismatch in handleCardClick functions
  - Updated ScriptsGrid.tsx and DownloadedScriptsTab.tsx to accept ScriptCardType instead of { slug: string }
  - This resolves the modal not opening when clicking script cards

- Fix server-side import issues
  - Updated autoSyncService.js to import from githubJsonService.ts instead of .js
  - Fixed path aliases in githubJsonService.ts to use relative imports
  - Updated scripts.ts to import from TypeScript service files directly

- Fix missing Install button
  - Resolved scriptDownloaderService.checkScriptExists method not being available
  - Install button now appears when script files exist locally

- Remove debug logging
  - Cleaned up temporary console.log statements and debug UI elements

All script card interactions now work properly:
- Cards open detail modal when clicked
- Install button appears when appropriate
- Server-side API calls work correctly
