Update tests to use new OcrmypdfPluginManager interface

Replace pm.hook.method() calls with pm.method() calls to match the
refactored plugin manager that now uses composition over inheritance.
The hook attribute is no longer directly exposed; instead, type-safe
methods are provided directly on the plugin manager class.
