fix: use v1 API for Gemini 2.5+/3.x models; show real error + generateContent filter

Browse Source 
- GeminiIntentService/VisionService: auto-select v1 for 2.5+ models, v1beta for older
- probarGemini: tries v1 then v1beta, shows actual API error message, filters model
  list to only those supporting generateContent so the user sees usable options
