[kbn/scout] disable side/solution tour before tests run (#245071)

## Summary

Original solution with local storage didn't work, so I use Kibana
uiSettings API to disable tours:

- `hideAnnouncements: true` should be set for each space
- Scout sets it for the default space when `samlAuth` fixture is loaded
(assuming first login attempt to be made)
- Scout sets it for the newly created space (parallel run)
 
I also added a log message to explicitly mention the environment we run
tests on:

```
 info [scout-worker] Running tests against MKI oblt project
 info [scout-worker] Reading cloud user credentials from /Users/dmle/github/kibana/.ftr/role_users.json
```

It should help us identifying misconfiguration when Playwright runner
gets a wrong configuration input file.
