Andrey Kolkov b099f8dde4 fix(kafka): fail closed when listing topics for an all-topics backup ...

In the empty-TOPICS (back up all non-internal topics) branch, the topic
list was resolved with a single pipeline under set -eu without pipefail:

  TLIST=$(kafka-topics.sh --list | grep -v '^_' || true)

The pipeline's exit status is grep's alone, so a real broker error
(unreachable / auth) that emits no stdout makes grep exit 1, || true swallows
it, and TLIST is empty - indistinguishable from 'no non-internal topics'. The
backup then drains nothing, tars an empty dir, PUTs it and reports success: a
silent empty backup a later restore would treat as authoritative.

Split the --list into its own command substitution so a broker error aborts
the Pod under set -e; filter internal topics only afterwards, so an empty
TLIST means genuinely no user topics.
