The download modal's step shared the 'locationStep' id with the import
modal, so getElementById('locationStep') could resolve to the wrong
element depending on template include order. The import flow relied on
an injected display:block !important rule to work around it.
Rename the download modal's step id and update all references so each
modal owns a unique step id.
Make the import modal a flex column with a scrollable step area so the
Back/Import buttons stay visible on short viewports (1080p / 150% zoom)
instead of being cut off at the bottom of the scroll flow.
Also reset step scroll positions via class since 'locationStep' has a
duplicate id in the download modal template.
