fix: lazy Gemini client init — server starts without GEMINI env vars

Browse Source 
The GoogleGenAI client threw at module load if AI_INTEGRATIONS_GEMINI_BASE_URL
was unset, crashing the VPS service. Now uses lazy singleton (throws on first use).
Routes return 503 gracefully when Gemini is not configured on the host.
