release: prepare v2.0.18 interface and reset reliability update

Preserve package progress and history across immediate cleanup, make extraction resets wait for all post-processing tasks, and keep archive diagnostics out of compact status cells. Rework account creation and settings selectors, improve context-menu placement, remove accidental row dragging, and expand regression coverage for the corrected workflows.
