ci: improve Codecov uploads; deflake kafka topics
Motivation: code coverage reports were incomplete. This lays a better
base for consistent reporting via GitHub Actions, with room for follow-ups.
It also removes a test flake source in Kafka jobs.

Impact: CI/tests only; no runtime behavior or ABI changes expected.

Before: Coverage uploads were inconsistent; Kafka tests could hang while
reading from /dev/urandom to generate topic names.
After: Coverage is collected with lcov and uploaded via a dedicated GH
Action; Kafka topics use fast $RANDOM-based hex, avoiding early-boot
entropy stalls.

Technical details:
- Add two workflows: "codecov base" and "codecov kafka" on Ubuntu 24.04.
  Use lcov capture with unexecuted blocks and prune common noise; upload
  with token for same-repo PRs and tokenless for forks.
- Update .codecov.yml: add path fixes for container (/rsyslog) and
  runner layouts; explicitly set comment: false and patch: false.
- Bump actions/checkout to v4 in existing workflows; add an actionlint
  job to catch YAML problems early.
- Switch codecov jobs in container matrix to 24.04 images.
- Improve run-ci.sh lcov invocation to be more tolerant of line/macro
  mismatches.
- Testbench: replace /dev/urandom topic generation with 8-char hex from
  $RANDOM; adjust diag.sh path/quoting for zookeeper helper.
