Move email templates from platform and use Mailchimp templates

[nomadbitcoin]

Currently, our platform sends event-based emails (e.g., course registration, live session notifications) using hardcoded templates with dynamic parameters via Mandrill and JavaScript. To improve email management, we need to:

1. Create and design email templates directly in Mailchimp.
2. Use Mailchimp’s API to trigger these emails based on platform events.

Tasks:

• Create email templates in Mailchimp for all necessary notifications.
• Store and use the Mailchimp Template IDs.
• Update API calls to Mandrill in the platform to trigger these templates.
• Pass dynamic parameters (e.g., user name, course details) to the Mailchimp API.
