pivot_to_long

Helper to reshape wide-format data (one row per person-tooth, surfaces
as separate columns) into the long format expected by <code>calc_dmft()</code>.

Computes dental caries indices (DMFT, DMFS, dmft, dmfs) from
surface-level clinical examination data and produces odontogram heatmap
visualizations of per-tooth-surface outcomes. Supports primary and
permanent dentition with configurable teeth per quadrant (5 to 8),
separate root and coronal caries tallying, long and wide input formats,
stratified output, and FDI/Universal/quadrant tooth numbering conversion.
