Scroll a long section nav instead of wrapping it onto a grid

Five or more sections wrapped onto a 3- or 4-column grid, which left the tab
bar's divider under the last row only and stranded every upper row's active
indicator against nothing. From five they are now what M3 prescribes and its
accessibility page defends: a scrollable tab bar, each tab as wide as its label,
offset 52dp. Four or fewer still share the row. The 20px icons take the 20 cut.
Plan: docs/plans/material-3-alignment.md, step 21 (navigation N-16).

The page's URL is `Livewire::originalUrl()`: while a Livewire component on the page updates, the
request is Livewire's update endpoint, and comparing with it left no section lit.
A row too long for its column wraps onto a grid rather than scrolling: below `large` (1200px)
five or six
sections go 3 + 3 and seven or more go four to a row — tabs that scroll hid the last sections on
a tablet. `label` names the navigation ("Sections"). Links use `wire:navigate` unless
Up to four sections share the row as fixed tabs. From five the row is M3's scrollable tab bar
each tab as wide as its own label, the set scrolling sideways, offset 52dp from the leading
edge so it reads as scrollable which is M3's own answer to a row that will not fit, and the
one its accessibility page blesses ("horizontal scrolling tabs meet accessibility requirements
because they need to increase in width to respond to label text without affecting the
layout"). An earlier version wrapped them onto a grid instead, which left the bar's divider
under the last row only and stranded the upper rows' indicators against nothing.
`label` names the navigation ("Sections"). Links use `wire:navigate` unless
`no-wire-navigate`. --}}
