Add pot/thermometer visualization to browser GUI

- Add volumen field to all sud JSON pot entries (30 L)
- Fix parseSudDoc to read from nested doc.pot (was using stale flat keys)
- SVG widget shows transparent rectangular pot with stirrer, thermometer
  with live temperature, and water fill level (water_mass/volumen) when
  a sud is loaded; no water shown when no sud is loaded
