feat: increase SquidWTF download service timeout to 5 minutes

- Download service was still using default 100s timeout
- Large artist responses and slow endpoints were timing out
- Now both MetadataService and DownloadService use 5 minute timeout
- Fixes 'The request was canceled due to the configured HttpClient.Timeout of 100 seconds' errors
