feat(dashboard): add stats footnote and min-h touch target to DashboardRecentDocuments

Adds stats?: StatsDTO | null prop; renders a quiet footnote showing total
document and person counts. Guards on stats?.totalDocuments != null so
zero is shown but the footnote is absent when stats fails. Adds
min-h-[44px] to doc rows for WCAG 2.5.5 touch target compliance.
Adds dashboard_stats_documents/persons i18n keys in de/en/es.
