Code-Level Confirmation

• extensions/voice-call/src/webhook.ts now enforces header gating and shared pre-auth body caps before reading attacker-controlled request bodies.
• extensions/voice-call/src/webhook.test.ts ships regression coverage for missing-signature, oversize, and timeout pre-auth webhook cases. OpenClaw thanks @SEORY0 for reporting.
