Build out notification table functionality

[cfisher36]

User Story: As a United Way member, I would like to be able to perform "Approve", "Reject", and "View Form" actions on the dashboard notifications table.

Description

Last sprint, Alex worked on building the UI for the notifications table. This sprint, we want to focus on making the interactive elements of the table functional. This will require that we link the "Approve", "Reject", and "View Form" buttons with their corresponding server actions.

Technical Considerations

• Most of your work will involve modifying the AdminDashboardNotifications component in src/components/AdminDashboardNotifications/index.tsx
• "View Form" should open the PDF form in a separate window.
• Reject server action is currently being worked on by Jackson in Reject server action #115
• Let us know if the PDF generation is broken in your working branch
• For this story, we also mentioned wanting to correct how the notifications table only retrieves pending agencies
