Each video row now carries a `metadata` dict aggregated from the
merged TSV: species, memory (STM/LTM), training_length_hr,
consolidation_length_hr, age, training/testing date-time, and
trained/naive fly counts. The UI renders these as a row of key:value
pills above the video, with the session role (training/testing)
colour-coded so the analyst can see at a glance what they're picking.
The merged TSV currently has duplicate rows per (date, machine, ROI);
the aggregator de-dups on those keys so counts aren't doubled. (The
duplication itself should be cleaned up upstream.)
