Fix 503 when Private GPT calls Ollama API on startup (Docker Compose ollama-api profile)

[meng-hui]

Fix for #2066

Description

When running private gpt with external ollama API, ollama service returns 503 on startup because ollama service (traefik) might not be ready.

• Add healthcheck to ollama service to test for connection to external ollama
• private-gpt-ollama service depends on ollama being service_healthy
