Drops the in-panel sanitize sub-block (button + preview table + "already sanitized" note) that duplicated affordances across the page. The header "Clear Data" button is renamed "Remove personal data" and now sanitizes the uploaded file and downloads the clean copy in one click - no preview, no confirmation. It is shown only when the source can be sanitized, and reads "Personal data removed" (disabled) when the file already looks de-identified. The old clearData() teardown is covered by Restart.
