Add view only settings for Local KB Admin

Purpose:
As per https://issues.folio.org/browse/ERM-2624 (view only settings for Agreements) it also makes sense to have view only options for the Local KB Admin settings

The way we split down the permission for users in Local KB admin currently is into two parts:

• "permissionName": "ui-local-kb-admin.kbs.manage"
• "permissionName": "ui-local-kb-admin.proxyServer.manage"

For consistency we should reflect the same structure for view only:

• "permissionName": "ui-local-kb-admin.kbs.view"
  • grants backend permission "erm.kbs.view" and ui permission "settings.local-kb-admin.enabled"
• "permissionName": "ui-local-kb-admin.proxyServer.view"
  • grants backend permission "erm.sts.view" and ui permission "settings.local-kb-admin.enabled"

A user with permissions ui-local-kb-admin.kbs.view should see the option to access the "External data sources" settings, and should see the External data source information but without the "New" or "Actions" buttons

A user with permissions ui-local-kb-admin.proxyServer.views should see the option to access the "Proxy server settings" and should the Proxy server information display but without the "New", "Delete" or "Edit" buttons
