Add support for "from_name" field in email notifications

Introduced a new optional "from_name" attribute to email settings, allowing customization of the sender's display name in outgoing emails. Updated backend models, APIs, and front-end components to include and handle this field properly. This enhances email clarity and personalization for users.
