Remove reflection-based registry lookup in favor of Camel's public API

[Copilot]

SampleAdminMcpBindings was using reflection to access the protected registry field on org.apache.camel.main.Main, which is brittle across Camel versions and can trigger illegal-access warnings/errors. Camel's Main already exposes a public lookup(String, Class) method backed by the same registry.

Changes

• Removed lookupFromRegistry(Main, String) and import java.lang.reflect.Field
• Replaced all 6 call sites with main.lookup(name, Object.class)
• Simplified bindIfMissing, lookup, and required — the redundant dual-lookup (registry + main.lookup) collapses to a single call

Before:

private static Object lookupFromRegistry(Main main, String name) {
    try {
        Field registryField = Main.class.getDeclaredField("registry");
        registryField.setAccessible(true);
        Object registry = registryField.get(main);
        return registry.getClass().getMethod("lookupByName", String.class).invoke(registry, name);
    } catch (Exception ignored) {
        return null;
    }
}

After:

private static Object lookup(Main main, String name) {
    Object value = main.lookup(name, Object.class);
    return value != null ? value : new ObjectMapper();
}
