carsten 0ee6ef2e68 Add sudo-style elevation for superadmin actions
CurrentSuperuser now requires a short-lived (5 min) elevated JWT
claim in addition to the is_superadmin flag, obtained via the new
POST /auth/elevate (no re-authentication — the user is already the
only superadmin in practice; this is a deliberate-confirmation guard
against accidentally triggering a destructive action, not a defense
against a stolen session). Regular login tokens keep working unchanged
for all non-superadmin routes; DELETE /participants/{id} from task 5
now needs a fresh /auth/elevate call, no other code changes required
since CurrentSuperuser's meaning changed underneath it.

create_access_token gained an extra_claims param (backward compatible)
to carry the elevated flag.
