feat: cache logos locally, show config_path, rename Sync button (#511)

- logoCacheService.ts: download script logos to public/logos/ for local serving
- cache-logos.ts: build-time script caching 500+ logos from PocketBase
- scripts.ts router: resolve local logo paths, resyncScripts now caches logos
- autoSyncService.js: cache logos during background auto-sync
- ScriptDetailModal: show config_path per install method
- ResyncButton: renamed 'Sync Json Files' to 'Sync Scripts'
- GeneralSettingsModal: updated auto-sync description text
- .gitignore: ignore public/logos/ and data/*.db
