add Api4 SettingsMeta entity and AdminUI Settings Inspector screen

[ufundo]

Overview

Adds an Api4 entity for inspecting settings meta and values.

Before

• Lots of settings meta, not very discoverable

After

• Find settings with a directory style format

Technical Details

Want to be careful about exposing sensitive values through the current_value key. Added a new is_secret to DSN and Password settings, but probably should be used in more places.

I could be convinced to hold back on the current_value column for now.

@ufundo how is this different from the other Api4 Setting entity?

[michaelmcandrew]

@colemanw - this might help answer your question civicrm/civicrm-docker#5

@ufundo - is there a link to a site where I can test this or should i do so locally?

[ufundo]

@colemanw this one is reshaped to be a more standard entity, so it can work with SearchKit

@michaelmcandrew see here on the test site: http://core-31592-4jwhi.test-1.civicrm.org:8003/civicrm/admin/settings-inspector

@totten just tagging you here as I remembered we talked about setting discoverability back in Ashbourne, interested in your thoughts
