fix: add Azure AI Foundry URL support for custom providers 

Detects Azure AI Foundry URLs (services.ai.azure.com and
openai.azure.com) and transforms them to include the proper
deployment path (/openai/deployments/<model-id>) required by
Azure's API. This fixes the 400 error when configuring OpenAI
models from Azure AI Foundry.

Fixes openclaw/openclaw#17992
