[VMS] Causes list on non-profits tab

[PC98]

• We have to show the causes list on the non-profits tab. The UI and data will be identical to what gets shown on the events tab.
• Create a component, like NonproiftsPageMainComponent.tsx that like EventsPageMainContent.tsx renders the causes list.
• Ideally we want to avoid duplicating code. If in [VMS] Break-up EventsPageMainContent to avoid re-renders #330 a re-usable component was created for the causes list, use that directly.
• If [VMS] Set-up UI for non-profits filtering page #361 has been completed, render NonproiftsPageMainComponent as part of the nonprofits page unfiltered component.
