Sets the contractor's main rate, the same way an employer's rate edit does. A main rate without a
service_start_date is updated in place and keeps its id. A main rate with one belongs to a
Statement of Work and is kept: seeding adds a new main rate beside it, and the list endpoint
returns both while that Statement of Work is in force. This lets the rate endpoints be exercised
without going through contract signature. Contractor of Record contractors, including ones not
active yet, and Contractor Management Plus contractors whose contract is signed cannot be seeded,
since their Statement of Work sets the rate: the endpoint returns 422.

The currency is derived from the legal entity the contractor is paid in by. A rate in a
currency the contractor cannot be paid in is rejected with 422.

This endpoint is only available in Sandbox, otherwise it will respond with a 404.
