AI agent configuration and environment reference

[codebestia]

Write apps/ai_agent/docs/configuration.md: every environment variable and setting the service reads — the OpenAI API key, model selection, Weaviate connection details, host/port — plus startup behaviour when one is missing.

Acceptance criteria:

• Every variable documented with required/optional status and default
• Documents the missing-API-key behaviour precisely: /health still returns 200 while /chat returns 500, which is deliberate and load-balancer-visible
• Documents Weaviate connection configuration and the failure mode when it is unreachable
• Cross-links the repo-wide environment reference
