Feat/auto group (#6590)

* feat(token): support custom auto group order

* feat(keys): enhance auto group presentation

* fix(keys): rework Auto flow border and compact inherited order

The Auto group highlight previously tinted the whole control surface
with a gradient and animated only a 1px top sweep, which read as a
background color rather than a flowing border. Replace it with a
border-only effect: an aria-hidden, pointer-events-none overlay whose
conic gradient is masked down to a thin ring hugging the rounded
perimeter, so the highlight travels around all four edges and corners
every 3.2s. The interior stays neutral with a restrained static
primary border and glow; prefers-reduced-motion hides the moving
layer while keeping the static emphasis.

The inherited global Auto order also rendered as spacious two-line
rows with circular sequence markers, wasting drawer space. Render it
as a compact wrapping strip of one-line chips (index, name, ratio
badge) with descriptions kept accessible via title and sr-only text,
scrolling only past a much smaller max height.

Custom add/remove/reorder editing, empty-array inheritance semantics,
and the submit payload are unchanged.

* fix(keys): preserve Auto inheritance and unify effects

* refactor(keys): temporarily disable AutoGroupBadge in api-key-group-cell
