fix: skip model API requests when no auth token is present (#643)

Prevents infinite retry loop on /api/hermes/available-models when
accessing the app without a token, which triggers server-side 429
rate limiting. Both loadModels() and fetchProviders() now bail out
early if hasApiKey() returns false.

Closes #606
