Mateusz Pusz aa2f91346d docs: document the two-axis quantity character ...

Rework the "Character of a Quantity" chapter for the order x field model and record the change
in the changelog.

- character_of_a_quantity.md: two-axis framing up front; a new "Real and complex quantities"
  section; the `quantity_tensor_order`/`quantity_field` enum and `quantity_character` struct
  definitions shown before use; an expanded ordering example (explicit vector, inherited
  vector, explicit tensor) and a complex declaration; the ISO 80000-2 rank-ordering quote; and
  the experimental warning removed. Deprecated `quantity_character::vector` examples updated to
  the two-axis spelling.
- CHANGELOG.md: 2.6.0 entries for the two-axis split, `cartesian_tensor`, the
  `numeric_field`/`tensor_order` customization points, the flat-enum deprecation and
  customization rework, and the magnitude/decomposition fixes.
