HAL9000 717a05f604 fix(security): fix plugins/loader.py load_from_entry_point security #7476
Parse entry point targets before import so allowlist enforcement happens prior to execution and add a Behave regression scenario covering the disallowed-prefix path.

"""Behave step definitions for the Plugin Architecture Framework.
Covers PluginState, ExtensionPoint, PluginDescriptor, PluginLoader,
