HAWNG-395: Handle warnings and false-positives

* .gitleaks.toml
 * Provides an extension config which lists the false-positives that
   should be ignored

* generate-.*\.sh
 * Fixes shellcheck warnings is assignments

* nginx.sh
 * Removes pipefail setting as non-POSIX and since pipes not actually used
   in script then removed entirely
 * Replaces bash (-v) which POSIX compatible equivalent

* ws-handler.ts
 * Checks the origin of the MessageEvent. Since the messages are expected
   from the cluster they should only comes from ${APP_HOST}/master so any
   other origin is not appropriate so should be ignored

* .snyk
 * Exclude non-production files from snyk analysis
