compute-guard: drop :8099 from the Talk-engine ports (false positive); Deepgram template line under the BYOK exemption

Hub classification 10-02: :8099 in windy-pro is the OLD translate-api / cloud-storage service, not Windy Talk
(verified: windytalk has no :8099, only lockfile hash fragments). DEEPGRAM_API_KEY in windy-pro .env.example is
a template line for the user-own-key Deepgram feature: owner-approved, approved_by windy-hub, expires 2026-12-31.
