PLU-388: Postman Max 50 recipients

[kevinkim-ogp]

Problem

Postman limits each email to have a maximum of 50 recipients (including the primary recipient, CC recipients, and BCC recipients), but Plumber does not implement this check.

Solution

• Add validation on the list of CC recipient emails

Improvements:

• Add validation on the list of CC recipient emails and throw error before attempting to call the Postman API.

Before & After Screenshots

BEFORE:
NA

AFTER:

Tests

• Existing emails can be sent correctly
• Step error thrown when more than 49 recipients included in the CC field
