+/**
+ * {@link RuntimePropertiesProvider} that enumerates application properties from the Spring Boot {@link
+ * ConfigurableEnvironment}. These properties are used for display purposes only (e.g. the Properties dev console) and
+ * do not affect Camel's placeholder resolution.
+ * <p>
+ * Property sources that represent environment variables, JVM system properties, and Spring Boot internals are skipped
+ * to avoid noise — only application-level configuration is included. However, camel/spring/server/management keys from
+ * env/sys sources are still included since they represent application configuration.
