Pull Request Overview

This PR refactors path handling in the Django settings template to use pathlib.Path and introduces a dynamic EMAIL_TEMPLATES list for auto-discovery of email templates.

• Add EMAIL_TEMPLATES loop to gather all .html and .txt email templates under admin/email
• Introduce DEFAULT_FROM_EMAIL and consolidate EMAIL_FROM assignment

• Ensure you have from pathlib import Path imported at the top of this settings file, or this will raise a NameError at runtime.

    BASE_DIR = Path(__file__).resolve().parent.parent

• Verify the indentation of the added EMAIL_TEMPLATES block matches the surrounding code block to avoid unintended YAML formatting issues.

    EMAIL_TEMPLATES = []

• Consider adding unit tests to ensure EMAIL_TEMPLATES is correctly populated based on the available template files.

    EMAIL_TEMPLATES = []
