/**
 * The overview's data section: wiki backup and migration. The header line
 * reports the host's scheduled-backup knobs and on-disk count (hidden until
 * `listBackups` settles). Export downloads
 * the whole wiki as one dated JSON snapshot; import walks a three-step flow
 * — pick a file, review its summary (per-table row counts and the export
 * timestamp), then choose merge (existing keys are skipped, never
 * overwritten) or replace (a red-armed second confirm, since it wipes all
 * six tables first) — and ends with the per-table imported/skipped counts.
 * A successful import re-fetches every loaded slice host-side.
