Update Ollama docs and UI to mark model as required

The model field must be set and the model must be pre-pulled in Ollama
before the container will work. Updated README, HOW-TO-USE, and the
ProjectCard UI label/tooltip to reflect this.

 - **Base URL** — The URL of your Ollama server. Defaults to `http://host.docker.internal:11434`, which reaches a locally running Ollama instance from inside the container. For a remote server, use its IP or hostname (e.g., `http://192.168.1.100:11434`).
