fix: harden upload cancellation and audit logging

Preserve pre-start and batch cancellation requests, reject late upload success after cancellation, and wait for cancellation acknowledgements before removing queue entries.

Separate formatted link logs from privacy-safe source cleanup and upload plan audits, persist audit fallback paths, redact support bundles, and expose audit diagnostics safely.

Improve queue selection and destructive-action clarity, show the Settings save action only while changes are pending, and add regression coverage for all updated behavior.
