[P2] Confirm grok-4.5 is a live model ID on api.x.ai before merging

This flips the xAI default from grok-4 to grok-4.5 (also in internal/providermodelcatalog/catalog.go). If grok-4.5 is not served by api.x.ai (or the ID differs, e.g. grok-4-5), every default xAI request 404s on first use. grok-4 is retained as "previous flagship" so a revert is trivial. Could not verify without API access.

xAI /models endpoint is gated by token/credits but you can see the model ID via openrouter open endpoint.

curl -s https://openrouter.ai/api/v1/models \
  | jq '.data[] | select(.id | startswith("x-ai")) | {id, name}'
