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.

The QUANTITY_SPEC parser only recognized `quantity_character::` as a character override,
and the generated metadata-extraction program `switch`ed over the character enum. Both
broke once the ISQ definitions moved to the `quantity_tensor_order` / `quantity_field`
spelling and `quantity_character` became a struct.
- Treat `quantity_tensor_order::` and `quantity_field::` (alongside `quantity_character::`)
as character overrides when deciding whether the third macro argument is an equation.
- Rewrite `character_to_string` to compare against the two-axis values instead of switching
on an enum.
The regenerated reference is byte-identical (only the source hash changes).
