[Sponsors page] Improve display of Sponsors and their logos
Feature Request
https://scipost.org/sponsors/ lists all current sponsors and, for organizations that approve it, displays their logos. However, the size of each entry is arbitrary. Please make a nicer display with homogeneous sizes and that is more human-friendly.
The list also only shows organizations with an active subsidy as of today. This leaves out recent sponsors with whom we may be negotiating a renewal. We should display the "recent sponsors" as well, until ~3-6 months after the end date of their subsidy, perhaps in a separate section to distinguish from current sponsors.
