When labelHidden=true the Label's visible width collapses to ~16 px
(the surrogate width), giving a ~16×18 px hit area below the WCAG
2.5.8 24×24 minimum. Adding min-h-6 / min-w-6 (24 px each) to the
Label class ensures the clickable region is at least 24×24 regardless
of slot content. With a visible label the Label still expands with its
text content as before.

Adds the audit fix-doc manifest entry referenced by this PR's
A11y-Audit-Ref trailer, so the triage workflow resolves the slug
instead of labeling it a11y:broken-ref.

Subject: [PATCH 3/3] fix(a11y): center checkbox in the 24x24 target when
 labelHidden
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With min-w-6, a labelHidden checkbox's <label> collapses to 24px wide while the
visible 18px surrogate sat flush-left (6px of dead space on the right). Add
justify-center only when labelHidden so the surrogate is centered in the hit
area (3px on all sides). Visible-label checkboxes are unaffected — the surrogate
stays left, next to its text.
