feat(web): drop the XP block from the combat victory screen

Design ruling R16: the victory screen removes the data-reward-experience
element and its "Erfahrung" line outright rather than hiding them behind
a conditional. CombatReward is now { silver, items }.

The surviving spec assertion checks that [data-reward-experience] is
absent, so it would genuinely fail if the block came back -- rather than
merely observing that some text changed.
