Split the closing of a Settlement Matrix in order to close a matrix without settling at the same time

[koekiebox]

Goal:

As a hub operator

I want to be able to CLOSE a batch

so that a batch may be closed without actioning the settling action, which will allow a hub operator to alternatively dispute a CLOSED batch

Acceptance Criteria:

• Refactor closeSettlementMatrix to only mark batches as CLOSED and not perform the settlement action
• Introduce executeSettlementMatrix which will mark batches for a matrix as CLOSED and SETTLED (perform the settlement action)
• Add domain unit tests to cover the above scenarios
• Introduce negative test cases

Complexity: <Medium>

Uncertainty: <Low> N/A.

Tasks:
Currently when closeSettlementMatrix(secCtx: CallSecurityContext, id: string): Promise<void> { function is invoked, the settlement batches will be closed as well as the settling process kicked off.
Instead, the closeSettlementMatrix(secCtx: CallSecurityContext, id: string): Promise<void> { should only CLOSE the batches for a matrix.

A new function called executeSettlementMatrix(secCtx: CallSecurityContext, id: string): Promise<void> { should be introduced, which should:

• Close any of the OPEN batches for the matrix
• Process the settling for the batches
