The old slider defaulted to floor(avg observations) — on heavy-tailed data
the average sits above the 75th percentile, so the first visit hid most of
the graph. Worse, the default (e.g. 98) exceeded the slider's max of 50:
the browser clamped the control while the label kept showing the unclamped
value, so the label lied about the active filter.
- slider position now maps logarithmically onto 1..max(observation_count),
rescaled whenever edge data loads, giving fine control at the low end
and full reach into the tail
- first-visit default is the median observation count of the loaded edges
- the persisted value is the threshold itself, so it stays meaningful when
the scale changes (e.g. switching evidence modes)
- label shows the threshold plus live 'shown/total edges' feedback
