### What problem does this PR solve?
**Cohere rerank base_url default handling**
- Background: When no rerank base URL is configured, the settings
pipeline was passing an empty string through RERANK_CFG →
TenantLLMService → CoHereRerank, so the Cohere client received
base_url="" and produced “missing protocol” errors during rerank calls.
- What changed: The CoHereRerank constructor now only forwards base_url
to the Cohere client when it isn’t empty/whitespace, causing the client
to fall back to its default API endpoint otherwise.
- Why it matters: This prevents invalid URL construction in the rerank
workflow and keeps tests/sanity checks that rely on the default Cohere
endpoint from failing when no custom base URL is specified.
