feat(orders): add resync and delete order buttons

Resync soft-deletes from Oracle then re-imports from GoMag with fresh
article data. Delete soft-deletes and marks DELETED_IN_ROA. Both have
invoice safety gates (refuse if invoiced or Oracle unavailable).

UI: split modal footer (Delete left, Resync+Close right), inline
confirm pattern (no native confirm()), dashboard row hover action
icons, disabled+tooltip for invoiced orders. 8 unit tests for safety
gates and happy paths.
