Clear call forwarding for a line

DELETE/api/lines/{sendblue_number}/call-forwarding

Removes the per-line call forwarding number. After clearing, inbound calls will fall back to the company default forwarding number (if configured).

This operation is idempotent — calling it on a line with no forwarding set returns 200 with forwarding_number: null.
