Fix: Migration command compatibility with packages overriding makemigrations/migrate

  Adds dynamic base class lookup to makemigrations and migrate commands. Both commands now scan INSTALLED_APPS and inherit from any custom commands found, ensuring PGViewsAutodetector is applied while preserving customizations from other packages (e.g., django-linear-migrations).

  - makemigrations/migrate commands use import_module to find custom commands
  - Continues through INSTALLED_APPS after django_pgviews to discover overrides
  - Falls back to Django's default commands if none found
  - Bumps version to 1.1.0
