ux(nav): pin active tab-strip chip to the scroll start

The Settings + Admin shells centred the active chip via
`scrollIntoView({ inline: "center" })`. On narrow viewports the
strip over-scrolled past the leading chips so the first one or two
were unreachable until the user manually swiped right. `inline:
"start"` lands the active chip at the leading edge so the trail of
preceding chips remains visible.
