Fix Open WebUI tests in offline mode

Browse source 
Open WebUI 0.9.6 still initializes its embedding function during startup, even when OFFLINE_MODE=true and BYPASS_EMBEDDING_AND_RETRIEVAL=true. With OFFLINE_MODE=true and no cached SentenceTransformer model, startup failed with:

ValueError: No embedding model is loaded. Set RAG_EMBEDDING_MODEL to a valid SentenceTransformer model name, or configure an external RAG_EMBEDDING_ENGINE (ollama, openai, azure_openai).

Configure the tests to use a dummy Ollama embedding endpoint so startup does not try to load or download a local embedding model. The endpoint is not meant to be contacted by these tests; it only keeps startup on the external embedding configuration path.
