revert: move scan counts back above the tabs + fix tab centering

Reverts 1aeea23 and folds in the actual fix the relocation was
chasing: the Scanner / Scanned tab labels were rendering with
their icons and text mis-aligned because TabsTrigger wraps its
slot in an inline `<span class="truncate">`. A `gap-1.5` on
TabsTrigger never reached the icon/label children. Wrap each
trigger's content in an `inline-flex items-center gap-1.5` span
so the icon and label share a real flex container.
