 * Normalise a backend base URL so a bare host/IP (no scheme) still resolves.
 *
 * Users routinely paste an Ollama address as `192.168.1.50:11434` instead of
 * `http://192.168.1.50:11434`. `fetch("host:port/api/tags")` then fails URL
 * parsing and the instance silently ends up with an empty model list. If the
 * value already carries a scheme (`http`, `https`, …) it is left untouched.
 * Trailing slashes are also stripped so `new URL`/`/models` concatenation is
 * stable.
