Prevent Refunds for Routing Slips prior to the cheque being deposited

* As a SBC Finance member
* I want refunds to be blocked on a routing slip until a predetermined amount of time has passed
* so that we can prevent a situation where a refund is approved before the original funds are deposited into the bank

**Acceptance Criteria**

**Scenario 1: Preventing refund before clearing time**
* GIVEN ... a routing slip exists in the system in the refund requested
* WHEN ... I try to approve a refund request
* AND ... it has not been more than XX days
* THEN ... I should be prevented from approving the refund and see an error message explaining why

**Dependencies? What is the impact of this dependency? (If so, link dependency in the ticket, make it visible in a team´s backlog)**
* Do you know a possible contact person to reach out (from the other team)?

**Validation Rules? (If yes, list here)**
