Add an initial cost for concept private rent contracts

Adds an initial cost to a concept residential lease contract.

Initial costs are one-time charges billed to the tenant at the start of the lease, such as a key deposit or nameplates, as distinct from the recurring contract lines.

A developer calls this endpoint while assembling a draft contract's initial charges, before the contract is finalized.

The cost is always attached to one specific real estate object within the contract, so both the contract's external identifier and the object reference must be supplied together.
