Free-account call limits

Accounts that have never added credit and never subscribed now run with two guardrails: every call is hard-capped at 5 minutes (regardless of any configured maxCallDurationSeconds), and at most 2 calls can be in progress at once, inbound and outbound combined. An outbound call over the concurrency limit is rejected with a new 429 error (code call_limit_reached); an inbound call over the limit is declined. Both limits lift permanently the first time you add credit or start a subscription. See Free accounts.
