[Feature Request] Indicate how up-to-date every source of data is

[AbhiramTadepalli]

Overview

Trends uses multiple sources of data, but each one has a different level of recency and time ranges

Proposal

• Identify all the sources of data we use
• Print the date range of each data source to the console
• Indicate the recency of the data in the website (need to wait for Design)

This could be done in a footer similar to the one being added to rooms: UTDNebula/utd-rooms#120
