Subject: [PATCH] feat(#553): move 7-tap Experimental unlock from About row to
 Build row

Follow-up to #509. Settings is post-connect, so About had no availability edge,
and wrapping the About version subtitle fought the About dialog's onTap. The
7-tap unlock now anchors on the Build (BuildInfo.stamp) row in Device Info,
mirroring Android's build-number gesture; About reverts to a plain row. The
countdown/unlock hint renders inline under the Build row.

Co-located on the #524 test branch so the owner tests one APK; will be split
to its own PR off dev at land time. Agent: QuietSnow (session 31eaba02)
