v1.0.2 - Doughnut chart fix

Fix: doughnut charts were corrupting the .pptx file. PowerPoint would report a content error and repair the file, and the chart slide ended up empty. The data-label position setting that caused it is now only applied to pie charts.

v1.0.1 - English translation

The parts the model and the UI see (schema docstring, valve descriptions, status messages, error/success messages, default labels) are now in English instead of Italian. No change in behaviour.
