feat(mail): switching category tabs replaces the history entry, as in Gmail (#161)

* feat(mail): replace the history entry when switching category tabs on a phone

Below md, a category tab navigates the inbox list frame with Turbo's
replace action, so the browser's Back leaves the inbox instead of
stepping back through every tab. At md and up the link keeps advance,
so desktop behaviour is unchanged.

The choice is made on click by the ui--tab-history controller, not on
connect: the tab strip is morphed on every list refresh, and a morph
removes attributes the server did not render.

* feat(mail): category tabs replace the history entry at every width

#150 asked for this on a phone only; the maintainer wants it everywhere,
as Gmail does. With no breakpoint to ask about, the tab links render
data-turbo-action="replace" from the server, so the click-time controller
goes: a server-rendered attribute survives the strip's morph on its own.
The account page's tab strip, added on main since, gets the same.

* docs(changelog): credit the tab history entry to #161, which took over #113
