Mint a browser softphone session

Step 1 of the two-step browser softphone handshake. Mints a WebRTC session (token + credential) the browser registers with the @telnyx/webrtc SDK. Once registered, call POST /v1/voice/calls/web/dial with the returned credentialId to place the call. The split avoids bridging to a browser that has not finished registering. The token lives ~1 hour (it must outlive the whole call, not just the handshake).
