[AF-39] Pre-Auction Notification for Participants

[ricardopacheco]

Issue number: resolves #39

Summary 🔴

This issue aims to implement a notification feature to inform participating users who have placed bids about the upcoming scheduled auction. The notification needs to be triggered automatically 1 hour before the auction starts, requiring the integration of an email delivery system with precise timing logic.

The notification content should include essential details such as the exact date and time of the auction's commencement, direct links to the auction platform, and any pertinent information, such as rules or additional instructions.

Proposed / Possible solution 🔴

• Following the already established pattern, we created the operation to process the auction reminder.

Checklist

• Create email template with corresponding content.
• Create a scheduled task after creating an auction to notify participants.
