feat(ui): AttrCombobox declare vs. consume semantics
Attr-string fields in the Custom Modifier Editor now differentiate
between declare-sites (seed-attribute.attr) and consume-sites
(add-to-attribute.attr, multiply-attribute.attr, add-aura.targetAttr,
absorb-damage-with-attribute.attr):

- Consume-sites hide the illustrative 'User-defined examples' group
  (ArmorPlates/BloodStacks/ManaPool) because those names are fiction
  unless something seeds them.
- Consume-sites surface a new 'Seeded in this descriptor' group
  populated from seed-attribute primitives elsewhere in the current
  tree (including inside trigger children via childPrimitives).
- Badge states: emerald 'seeded' when the typed value matches an
  in-tree seed; red 'not seeded' when it's a non-schema name with no
  backing seed; amber 'user-defined' only in declare-mode for
  off-catalog names.

Declare-mode behaviour is unchanged — inventing ShieldCharges there
still works without warnings.
