Fixes microsoft#2502. python-pptx exposes multi-level category paths via Categories.flattened_labels as tuples (e.g. ('2024', 'Q1'), ('2025', 'Q1')), but PptxConverter was only reading the leaf label via c.label, dropping parent labels entirely so a year/quarter chart produced two identical 'Q1' rows. Use flattened_labels to render each level of the category hierarchy as its own column. Single-level (flat) category charts are unchanged. Also keep the None->empty-cell fix from microsoft#2526.
