Fix SO management fulltext search

[pgayvallet]

Summary

Fix #154244
Related / workaround for #130616

Very old issue that happened again, this time for the slo type because of mapping incompatibilities with default searchable fields (and a limitation in our code we still did not address)

• Fix the slo SO type mapping for the name field (keyword => text)
• Add a integration test failing if any management type has incorrect mappings for searchable fields (mostly a workaround rather than fixing the root problem, but at least it will avoid that kind of scenario for the time being)

LGTM! Ideally, we should fix the actual bug that forces all name to be text instead of anything else.

Yeah, for sure, this isn't fixing the root cause. But it fixes the bug in 8.8.

FWIW I took a shot a long time ago at fixing it properly in #119618, but it was more complicated than I anticipated. I don't remember the details, unfortunately

LGTM! Thank you @pgayvallet!

This bug fix seems to break the SLO page. Opening an issue to track it
