Adapt to new airtable attachment policies

Airtable implemented a breaking change that prevents slmn.gg from displaying any images. In addition, mitigations will likely be needed to deal with Airtable's new expiring URLs in the long term beyond just allowing Airtable's new domain.

An update, the attachment changes also break the music player. This issue is resolved for now, but will break again come February when Airtable will force all users to their new expiring URL platform.
