Ask for SIP trunking to be enabled

Starts a request a human reviews. Refused 409 sip_trunking_request_pending while one is already waiting, and 409 sip_trunking_already_enabled if the organization can already create trunks. A rejected request may be resubmitted — read the reason from GET /v1/sip-trunks/entitlement first, since resubmitting unchanged wastes both sides.

Requires the admin scope. A key with less gets 403 insufficient_scope.

POST
/v1/sip-trunks/access-request
AuthorizationBearer <token>

Authorization: Bearer tone_live_… or tone_test_…. The prefix IS the environment: a test key reaches only the sandbox, and no request field bridges the two.
