fix: strengthen live recovery and support diagnostics

Apply account and key changes to active queues without a restart and isolate provider attempt cancellation so fallback accounts remain usable. Preserve pause ownership, bound persisted HTTP 416 recovery, reconcile resets with authoritative state, and stabilize package ordering and live update cadence. Correlate rotation, conversion, resume, disk, queue-control, clipboard, and support-export events while redacting sensitive data at every persistent boundary and again in generated bundles. Release as v2.0.31 with updated English documentation and regression coverage.
