fix(web): sweep every remaining fixture off level/experience/requiredLevel

Task 17 (final task) of Renown & Reputation Foundation. Fixes the last 3
compile errors blocking the web suite (app.spec.ts, world.store.spec.ts)
by aligning CharacterResponse fixtures to the real renown-only shape, and
removes the two remaining dead 'experience' reward-preview leftovers
(current-location fixture entry, location-icon glyph) now that the API
no longer seeds them. Full web suite: 24 files / 228 tests, all green,
for the first time this entire slice.
