- Global settings: custom AI panel with OpenAI/Gemini/Claude each with
API key, model selector, and live test-connection button (no save needed)
- Per-company IA tab: same three providers + fallback to global when empty
- AiBot: reads per-company config_json first, falls back to env() global
- Added callClaude() for Anthropic Messages API
- More OpenAI models: gpt-4.1, gpt-4.1-mini
- test-ai endpoint: accepts provider/api_key/model from POST for live test
