Settings: replace llama-server with Ollama, remove Local AI tab, rename Developer to Debug

- AI Provider: "Local (llama-server)" changed to "Ollama" with URL and
  model fields (defaults to localhost:11434, llama3.2)
- Ollama connects via its OpenAI-compatible API (/v1 endpoint)
- Removed empty "Local AI" tab
- Renamed "Developer" tab to "Debug"
