When a Zigbee device was approved (PendingDevice.status=approved + Node
created) and the user later deleted the canvas Node, the PendingDevice row
was left orphaned as approved. On re-import _persist_pending_import found
the existing row, refreshed its fields but left status=approved, so it
never reappeared in the Pending list (which filters status==pending) —
the import reported devices found but Pending stayed empty.
Reset such orphaned approved rows back to pending on re-import. Hidden
devices stay hidden (explicit user intent). Adds regression tests for
both revive-approved and keep-hidden paths.
