The panel drove a Flickable by hand: two Repeaters in a Column, plus an
ensureCursorVisible() that mapped each row into content coordinates and
moved contentY itself. That is the machinery a ListView already has, and
the hand-rolled version came with a 6px margin that scrolled the list
whenever the mouse merely rested near the viewport edge.
Flatten the remembered and discovered groups into one model whose entries
carry the section they came from, and let the view keep the current row
visible. Section headers are computed per index the way the network panel
does it. The cursor keeps working in section-relative terms, so
activation, forget, hover, and the hero toggle are untouched.
Positioning has to be deferred a turn: called straight out of
onCurrentIndexChanged it silently does nothing, because the model is
rebuilt every time discovery reports and the swap resets the view out
from under the call.
