Same defensive guard as legal-analysis + summarize, now applied to the
upload-zone and audio-zone handlers in tools.js. Affects redact,
timeline, and transcribe (which all share these zones via tools.js's
setupUpload / setupAudioUpload). Stops native label-for clicks and the
input's own click from bubbling into the zone handler that would
otherwise programmatically re-open the picker.
