fix(pricing): apply Anthropic long-context tiers to Claude calls (#1716)
Claude calls never used the LiteLLM above-threshold rates, so Haiku 5.5
requests over 100k prompt tokens (input + cache read + cache write) billed
at the base rate. claude joins TIERED_PRICING_PROVIDERS and the transcript
paths pass the provider. Long-prompt test fixtures move to Sonnet 4.6, which
has no tier, so their round figures hold.
