Remove deprecated register_permissions hook

- Removed register_permissions hook definition from hookspecs.py
- Removed register_permissions implementation from default_permissions.py
- Removed pm.hook.register_permissions() call from app.py invoke_startup()
- The register_actions hook now serves as the sole mechanism for registering actions
- Removed Permission import from default_permissions.py as it's no longer needed

This completes the migration from the old register_permissions hook to the new
register_actions hook. All permission definitions should now use Action objects
via register_actions, and permission checking should use permission_resources_sql
to provide SQL-based permission rules.
