ccm/ocm: Fix missing metering for 1M context and /fast mode

Browse Source 
CCM: Fix 1M context detection - use prefix match for versioned
beta strings (e.g. "context-1m-2025-08-07") and include cache
tokens in the 200K threshold check per Anthropic billing docs.

OCM: Add GPT-5.4 family pricing (standard/priority/flex) with
extended context (>272K) premium pricing support. Add context
window tracking to usage combinations, mirroring CCM's pattern.
Update normalizeGPT5Model defaults to latest known models.
