[feat](trx-frontend-http): one navigation model at every width

Eight destinations sat flat in the tab strip with equal weight, competing
with the controls for the same row and then scrolling out of reach with
only a fade to say so.  They are not equal: Radio is where an operator
spends nearly all their time, Bookmarks, Digital modes and Map are
operating surfaces, and Statistics, Recorder, Settings and About are
occasional.

The mobile layout already grouped them exactly that way, behind its More
menu, so the application carried two navigation models.  Adopt the mobile
grouping at every width instead of adding a third: four operating tabs
plus More.  The strip no longer scrolls at any width, and the menu keeps
its bottom-sheet placement on mobile while anchoring under its button
elsewhere.

Drop the labels between 701 and 1180px so the tabs degrade to their icons
— which every tab already carries — before the strip could ever need to
hide a destination.

Rename Main to Radio: it is the receiver, not a generic first page, and
the name now says what the destination is rather than where it sits.

Freeing that width also let the style picker and theme toggle return to
the bar inline, leaving only the layout picker in the overflow menu.

Navigating to About in the browser smoke test now goes through More, as a
person would.
