Andrey Kolkov 405eb25095 fix(backups): harden Kafka metadata backup
- Fail closed on topic listing: set -o pipefail, capture kafka-topics
  --list --exclude-internal exit separately, and abort on failure so an
  unreachable broker can no longer produce an empty backup reported as
  Succeeded. An empty list after a successful call stays legitimate.
- Check each kafka-topics --describe exit and validate the parsed
  partition count / replication factor before writing a record, so a
  timed-out describe cannot write a corrupt orders\t\t\t line.
- Store topic configs one per line with key and value in separate
  tab-delimited fields, sourced from kafka-configs --describe (one config
  per line), so a value containing a comma (cleanup.policy=compact,delete)
  round-trips; on restore each config is applied with the value bracketed
  only when it contains a comma.
- Detect topic divergence on restore instead of a silent --if-not-exists
  no-op: grow partitions with --alter when the backup asks for more, and
  fail loudly (naming the topic and both values) when it asks for fewer
  partitions or a different replication factor. A restore that cannot
  reach the recorded state no longer reports Succeeded.
- Add KafkaStrategyKind to the RestoreJob cleanup-dispatch no-op group so
  deleting a Kafka RestoreJob does not run a pointless Velero cleanup; add
  a regression test alongside the siblings, plus a reconcile Kind-gate
  test and a rendering test that actually renders the strategy template.
- Wire the kafka-metadata Chainsaw suite into both selectors
  (select-install suite_to_source, select-e2e src_to_suites) so editing
  the kafka app or the suite selects it and the bats unit tests pass.
- Pin the client image to the operator's default broker version
  (kafka 3.9.1) with a digest, and align the example default; fix the
  values comment. Point the RabbitMQ comment references (which shipped in
  the CRD description) at the Job strategy actually mirrored, and trim the
  in-pod comments that rendered into the manifest.
- Document the Strimzi Topic Operator caveat: for a topic owned by a
  KafkaTopic CR the operator reconciles its config from the CR, so an
  in-place config restore is durable only for out-of-band topics.
