/**
 * Adds ln__total rows at every dimension level (except the measure/leaf),
 * plus ln__grand_total rows at the top level, for every distinct leaf.
 *
 * Rules:
 * - Paths are split by "-->" (whitespace around segments is trimmed).
 * - The last segment is treated as the "leaf" (e.g., measure name).
 * - For every prefix group, we add a total row by replacing the next segment
 *   with ln__total and then appending the leaf.
 *   Example: A-->B-->C-->Leaf
 *     - A-->B-->ln__total-->Leaf     (totals across C within A,B)
 *     - A-->ln__total-->Leaf         (totals across B,C within A)
 * - For each distinct leaf, we add ln__grand_total-->Leaf.
 * - Output is ordered alphabetically (case-insensitive) within each group,
 *   with ln__total rows placed after non-total rows at the same grouping level,
 *   and ln__grand_total rows at the end.
