Fix Ollama: remove duplicate stale configMap in AIChatPanel

AIChatPanel had its own hardcoded configMap with the old llama-server
URL (localhost:8080) and field names (local_model_path). Every chat
message reconfigured the provider with these wrong values, overriding
the correct settings applied at startup.

Fix: replace the duplicate with a call to the shared configureAIProvider().
Also strip trailing slashes from ollama_url before appending /v1 to
prevent double-slash URLs (http://localhost:11434//v1).
