Alynt Drime Backups Dashboard 0.1.16

V2.2 dashboard-side action-history reconciliation and audit hardening. Adds additive client action report storage, stale-action reconciliation after successful status polls, clearer Site Detail action-history evidence, compact Sites-row latest-client-action hints, and Diagnostics aggregate action counts. This release preserves the existing safety boundary: no restore, delete, cleanup, schedule-management, credential, Drime-token, or arbitrary-command powers.
