Subject: [PATCH 1/2] refactor(app): add SetEnforceUniqueUsernames to restrict
 allowed values

Signed-off-by: jnelle <602579@fom-net.de>

* Since I couldn't find the allowed values in the GO SDK docs, I decided
  to add this, because it restricts the allowed values and shows the
developer which values are allowed
