[feat](trx-frontend-http): add Live/History views to WEFAX tab

Restructure the WEFAX tab to match the SAT/LRPT pattern with a
view switcher bar. Live view shows decoder description, live canvas,
and latest image card. History view adds a filterable, sortable table
of all decoded images with Clear All button.
