koko210Serve 4e28236b06 fix: preserve collapsible subsection state across polling re-renders ...

- Use stable section IDs (without Date.now()) so collapse state can be
  tracked across re-renders
- Snapshot collapsed state before innerHTML replacement, restore after
- Prevents the 10s polling from expanding all subsections every time
