fix(ux): quick wins from the usertest medium list

- audit type filter: 'Alle'/'All' capitalized like every other label
- settings -> setup wizard: close Settings first (one modal layer),
  stronger wizard scrim
- try-out setup profile discloses the upgrade path to a regulated
  profile
- store maturity pills explain themselves on hover (experimental/
  published/planned)
