HMT 53: Verify food tickets

[AnaCoda]

• Add admin page with a QR code camera scanner
• Admin selects an event to scan for from dropdown
• QR code is automatically verified when a new code is scanned (no button press needed)
• There is a Manual Scan button if you want to re-check a ticket
• When a QR code is scanned, it shows if the user can eat or not
• Also shows descriptive messages depending on the situation
• If the user is in the wrong specific time slot, they will be allowed to eat anyway

The changes to the Food create event form are not important at all, I just had to do it to test my changes and I thought I'd leave the changes there in case others want to use the form as well (since the old form had errors with new data model things)

@hannagracec will make it look nicer

Expanded on Ana's QR scanner UI:

Catered the UI to mobile view (assuming admins will be using their phone to scan the QR )

Example of the mark as attended button:

Also updated the navbar link and made it collapsable to work with mobile devices

Just some sample files that need to be deleted as a change to a file that was made that I don't think is needed
