fix(tools.func): fix meilisearch import-dump background process handling

When killing the background meilisearch process after dump import,
bash would print a 'Terminated' job notification and trigger
'pop_var_context: head of shell_variables not a function context'
errors (visible as /dev/fd/63 line errors), causing the rest of
the update_script to not execute. This left meilisearch stopped
after migration and caused subsequent update runs to skip it
(binary version already matched latest).

Two fixes:
- Redirect background process output to /dev/null to suppress
  meilisearch startup log noise in the update output
- Add 'wait $MEILI_PID' after 'kill $MEILI_PID' so bash properly
  reaps the child process without printing a job status notification

Fixes #14276
