fix(ui): show Reimporta button on DELETED_IN_ROA orders

mark_order_deleted_in_roa wipes order_items, so renderOrderDetailModal
hit the items.length===0 early-return BEFORE configuring footer buttons —
leaving DELETED_IN_ROA orders with no way to retry from the UI.

Extract the 3 button configurators (Retry/Resync/Delete) into
_configureDetailButtons() and call it before the early-return. Also
fire onAfterRender on the empty-items path for consistency.

Cache-bust shared.js v47 → v48.
