Enable procurement shop fee editing

[jonnalley]

User Story

As an OPS System Admin, in order to efficiently and independently manage procurement shop fee changes, I want to be able to set/change fee amounts and logic for different agreement types.

Acceptance Criteria

• [ ] An OPS System Admin has the ability to see current fee amounts and rules for each procurement shop and each agreement type
• [ ] An OPS System Admin has the ability to see current fee amounts based on any dollar amount ranges of a BL, depending on OPRE business rules
• [ ] The OPS System Admin has the ability to update and persist any fee amounts and the new rates/amounts be used successfully for any BL entered thereafter
• [ ] No additional or external approval is needed for the OPS System Admin to make these changes
• [ ] If #676 has been done by this point, any fee changes made need to be thoroughly logged for later auditing
• [ ] Once a BL is obligated, the fee amount/rate shouldn't change. But BLs in draft and in execution should update the fee/rate when these rates are changed

• [ ] Update/add backend business logic
