fix: add base64 encoded SquidWTF endpoints with automatic fallback

- Decode 6 endpoints at startup (triton, wolf, hund, maus, vogel, katze)
- Automatic fallback when endpoint fails
- All services cycle through endpoints on failure
- URLs stored as base64, decoded once in Program.cs
- Fixes search/download issues
