[Discover][Traces] Fix flaky explore_from_slo Scout test

[jorgeoliveira117]

Closes #265040

Summary

Fixes flaky Scout failure #265040 in explore_from_slo.spec.ts.

The APM availability SLO test navigates to the SLO History tab and asserts eventsChartPanel is visible. On cloud CI the page (SLO fetch + history charts) can take longer than Playwright’s default 10s expect timeout, so the assertion failed even when the UI was still loading normally.

Change: use a 30s timeout for eventsChartPanel and sliChartPanel visibility checks (same pattern as other traces Scout tests that use explicit CI budgets).

Hey @jorgeoliveira117, the last timeout-related failure was on April 22. The subsequent failures were due to a more general issue (about a month ago). I'd suggest closing the issue with a message explaining that there has only been one timeout failure in the last 1.5 months, keeping an eye on it and closing this PR. What do you think?

Metrics [docs]

Saved Objects .kibana field count

Every field in each saved object type adds overhead to Elasticsearch. Kibana needs to keep the total field count below Elasticsearch's default limit of 1000 fields. Only specify field mappings for the fields you wish to search on or query. See https://www.elastic.co/guide/en/kibana/master/saved-objects-service.html#_mappings
