[fix](trx-frontend-http): tidy up the map's filter bar

The bar explained itself in prose: "All bands visible by default" sat
between the chips and the next group, taking width the bar could not
spare and reading as a stray line of text. An "All" chip says the same
thing in a chip's width and gives the selection somewhere to be undone.

Band chips also came up dimmed at the very moment every band was on the
map -- an empty selection is no filter at all, so nothing is dimmed
until something is picked. The path toggles drop their "On"/"Off"
suffix, which cost most of a row and only repeated what their own
highlight already said; state moves to aria-pressed and the tooltip.

The rest is alignment. The rule dividing the buttons from the filters
is drawn on the button block's edge, and a centred block left it
floating as a stub beside a two-row bar; stacked, it lay down the left
of a block that sits underneath. The labels sat at their natural
widths, so each row's first control started somewhere different, and
the two pairs of phase buttons differed in width, so the groups after
them missed each other by four pixels. One gutter for every label, one
width for both pairs, and the search field moved last where it can take
the room the fixed-width groups leave.

The map layout test now covers the chips, the divider's height and the
rows' shared start.
