feat(scripts): two-axis character labels and a merged Traits column in the reference

Update the systems reference generator for the two-axis quantity character and to reduce
the quantities table width:

- The Character column now prints the order with a `complex` prefix only when the field is
  complex (`scalar`, `complex scalar`, `vector`, `tensor`, `complex vector`,
  `complex tensor`), replacing the old `Real`/`Complex`/`Vector`/`Tensor` labels that mixed
  the two axes and could not express complex vectors or tensors.
- The separate `is_kind` and `non_negative` boolean columns are merged into one `Traits`
  column that shows `kind` and/or `≥ 0` only when set (blank otherwise), dropping a column
  and the per-row ticks.

Regenerated the affected systems reference pages.
