chore(deps): apply dependency updates in one combined change (#694)

* chore(deps): apply dependency updates in one combined change

- Bump ansible-core to 2.19.11 and jmespath to 1.1.0 in requirements.in
- Regenerate the Python 3.11 pip-compile lock in requirements.txt
- Bump molecule-plugins to 23.6.0 while keeping molecule on the stable 6.x
  series (avoids the molecule-plugins 26 major jump that broke vagrant module
  resolution in CI)
- Bump ruamel-yaml-clib to 0.2.15
- Bump the zgosalvez/github-actions-ensure-sha-pinned-actions action to 5.0.6
  (SHA-pinned) in lint.yml

* fix(server): make log_destination conditional boolean for ansible-core 2.19

- The always block's 'Save logs of k3s-init.service' task used when: log_destination
  where log_destination is a path string derived from an env var
- ansible-core 2.19 rejects string-derived conditionals; evaluate the path as a
  real boolean (non-empty) check so the conditional is a true boolean
- Required to keep the k3s_server role working with ansible-core 2.19.11 (the
  dependency bump in this change)

* fix(verify): coerce regex_search assertions to bool for ansible-core 2.19

- ansible-core 2.19 requires assert conditionals to be boolean; regex_search
  returns a string, which is now rejected
- Wrap all regex_search results used in assert.that with | bool so the calico,
  cilium, metallb, and kube-vip image-tag checks produce boolean results

* fix(verify): use boolean is regex_search test instead of | bool

- | bool on a regex_search result coerces a tag string like v0.16.0 to False
  in ansible-core 2.19, failing the image-tag assertions
- Use the is regex_search test which returns a real boolean without string
  coercion for the calico, cilium, metallb, and kube-vip image assertions

* fix(verify): use is not none for regex_search assertions

- ansible-core 2.19 has no "is regex_search" test and rejects bool string
  coercion, so use the regex_search filter with an "is not none" comparison,
  which yields a real boolean for the image-tag assertions
- Applies to calico, cilium, metallb, and kube-vip image checks

* fix(metallb): retry transient apiserver resets in config tests

- The Layer 2 and BGP final configuration checks ran a kubectl get per
  resource with no retry, so a transient connection refused from the kube
  API could abort converge
- Mirror the download_retries/download_delay retry pattern used by the
  'Wait for MetalLB resources' task so these checks survive api server
  resets on slow runners
