[Enhancement]: Sort models in model selector

[juancarlosm]

Description

When models are fetched from a remote LiteLLM or OpenAI, they appear in the model selector in an unsorted order, making it difficult to find specific models.

Current behavior

Models appear in random order:

• OPENAI.o1-pro
• KUBEAI.phi4-reasoning
• GEMINI.imagen-3.0-002-model
• OPENAI.o3-mini
• ANTHROPIC.claude-sonnet-4-20250514
• (etc.)

Expected behavior

Models should be sorted alphabetically for better user experience.

Proposed solution

Add a sort operation in loadConfigModels.js after fetching models:

// Around line 102, after fetching models
for (const name of associatedNames) {
  const endpoint = endpointsMap[name];
  modelsConfig[name] = !modelData?.length ? (endpoint.models.default ?? []) : modelData;
  // Sort fetched models in ascending order
  if (modelData?.length && Array.isArray(modelsConfig[name])) {
    modelsConfig[name].sort();
  }
}
