Display the date range of the data

[tadamcz]

Hi, fantastic project!

Minor suggestion: prominently display (e.g. on the FAQ?) the date range of your data (e.g. "This website includes data on every market/question up to 23 June 2024"). At the moment it's a bit hard to tell how up-to-date things are, because even the market list view doesn't include any dates.

(How often do you run themis-fetch? Is it on a schedule or run manually?)

Thanks for the kind words! I think a last-updated line would be a great addition. At the moment I run the fetch script manually (and haven't done so in a few weeks, so thanks for the reminder).
