Migrate catalog-react and app blueprints to configSchema

Move EntityCardBlueprint and EntityContentBlueprint to the new
`configSchema` option using zod v3, and AppLanguageApi to zod v4.
Fix config schema merge in `makeWithOverrides` when mixing
`configSchema` and deprecated `config.schema` sources.
