Add howto-modul-erstellen.md covering the full module creation workflow:
scaffold, manifest, container registration, first page, sync, validate,
and test. Includes 9 extension point examples, merge checklist, and
troubleshooting table. Documents the AuthorizationPolicy container
registration requirement (policies with constructor params must be
explicitly registered). Update make:module command output to reference
the tutorial, manifest contract, and notifications as reference module.

make:module <id> generates the full module directory structure with
manifest (all 18 fields), ContainerRegistrar stub, AuthorizationPolicy
stub, and empty pages/templates/web/tests directories. Prevents
duplicate IDs and invalid formats.
module:validate <id> (or --all) checks manifest parsing, class existence,
interface compliance, namespace rules, permission key format, template
file existence, and dependency resolution — catching errors that would
otherwise only surface at boot time. Temporarily registers module PSR-4
paths so non-enabled modules can be validated too.
