Port Allocation Change Request features to Allocation Requests

[dsajdak]

With the allocation change request feature we modified some of the process flow. This process should be ported back to the allocation requests for a more seamless process across the two. What to update on allocation requests:

Allocation detail page:

• Expose button to add 'notifications' so admin can include details about allocation request
• Allow 'lock/unlock' to be set here like the 'allow change requests'

Allocation request list:

• Change 'Date Requested/Last Modified' to 'Last Modified'
• Change 'Allocation Actions' to 'Actions'
• Add 'Details' button to get to Allocation detail page
• Unlink ID number as this will now be the 'Details' button
• Grey out 'Activate' if allocation is new - this is because allocation attributes need to be added to new allocations before allocation is approved
• Remove 'Deny' button and require admin to use 'Details' to specify a reason for denying an allocation

After discussion, we decided:

• Activate button on 'Allocation Requests' list will be greyed out for new allocations, forcing admin to view the allocation details
• We will not require allocation attributes but admin will get a pop-up asking if they're sure they want to activate an allocation with no attributes
• Also will not require a reason for a denial but admin will get a pop-up asking if they want to provide a reason
