Fail the build when a trust-store listing fails.

Without pipefail, a first keytool -list failure that produces no usable output can leave the while loop with no aliases and an exit status of zero. A final keytool -list failure with no matching output can make grep return nonzero, which ! converts to success. Check both keytool -list exit statuses before parsing or accepting their output.

Apply this correction to all eight identical Dockerfiles, including the three .choreo files. The ROOTS expression is anchored to ^Owner: and cannot match Issuer: lines, so the regex does not need a broader change.

Review comment at @deployment/development/docker/neo4j/Dockerfile around lines
34 - 37:
Update the trust-store cleanup pipeline so both `keytool -list` invocations must
succeed before their output is parsed or accepted; do not let the alias loop or
negated `grep` turn a listing failure into a successful build.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
