req.user is never populated in agent-service (Kong verifies JWT, no Passport strategy).
This caused userId to always be undefined → system prompt had no 'Current User ID' →
Claude used tenant slug 'shenzhengj' as userId → DB error 'invalid input syntax for
type uuid'.
Fix: decode JWT payload from Authorization header (no signature verify needed — Kong
already verified it) to extract sub (user UUID) for both AgentController and
VoiceSessionController.
