Show how each bot message was generated

Every bot message gets an info button that opens its details: the
provider and model behind it, tokens and cost, the job that ran it, each
model used and every call in order. Each model call now records how it
was made in token_usages.settings (generation settings sent, whose
settings they were, pinned or automatic model, fallbacks), shown per
model in the modal.

Live replies now carry their token usage, from the job's push and the
live relay alike, so it shows without a reload.
