[fix](trx-frontend-http): stop Tools lighting up on every refresh

navigateToTab marked the Tools button by asking whether the destination
tab was displayed, which is the right question at the wrong moment: the
first route navigation runs while the card is still behind the loading
state, where every tab computes to display:none.  Refreshing or deep
linking to any page therefore lit Tools alongside the real destination,
and nothing re-evaluated it once the page appeared.

Membership of the Tools menu answers the same question without needing
anything laid out, and still reads the grouping ui-core installs rather
than a second copy of it.

The smoke fixture now serves the SPA shell for route paths the way the
server's per-tab index handlers do, so a deep link no longer 404s and
the case is testable at all; two of them are asserted.
