Bulk Archive Unavailable Items

[michellejli77]

Description

This PR allows admins to bulk archive all unavailable items older than a specified number of days. Specifically, the archiveByDays API function is altered to allow filtering on availability. This allows admins to easily archive unavailable items, which reduces the number of active items on the front page of the website.

Closes #178

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

• Check that the bulk archive button only archives unavailable items
• Check that string inputs and negative numbers for the days prompt an error

• Node.js version: 14.18.0
• Desktop/Mobile: Desktop
• Browser: Chrome
