dataset cards show # of subjects as a ratio of total in dataset

[surchs]

On the dataset card there is a text that shows what node API the result is coming from, e.g.

ignore the "from OpenNeuro" part for this guy, we'll deal with it in #279

This should work both in federated and node-direct mode. In node-direct mode all datasets should show the same "from" text: that of the node API that is being queried.

TODO

• each dataset has a visual indicator (e.g. text as now) of both the # subs in the cohort, AND the total # subs in the dataset

Related to neurobagel/api#216

One thing we should consider doing is to have this work as well for the global subject counter.
