feat(classifier): Anthropic-specific guidance for subscription exhaustion

When an Anthropic Claude Pro/Max OAuth subscription hits the "out of extra
usage" 400 (now classified as billing), surface actionable guidance pointing
at claude.ai/settings/usage and the cycle-reset option instead of the generic
"add credits with that provider" line — which does not apply to a
subscription. Folds in the UX from #40073 (@harsh-matchmyflight) without the
extra FailoverReason enum; the billing reclass already provides the recovery
behavior.

"""Tests for the Anthropic-subscription branch of
``agent.conversation_loop._billing_or_entitlement_message``.
Regression context: Anthropic Claude Pro/Max OAuth subscriptions surface
exhaustion of the metered "extra usage" bucket as a hard HTTP 400
("You're out of extra usage. Add more at claude.ai/settings/usage..."),
which classifies as ``FailoverReason.billing``. The generic billing
guidance ("add credits with that provider") is wrong for a subscription
the user waits for the cycle reset or switches to an API key. This branch
gives Anthropic-specific, actionable guidance (folds in PR #40073's UX).
