Description:
Recent feedback on the new email design suggests that listing individual transactions (especially in large numbers) is not very helpful, and including detailed data in emails may introduce security and privacy risks. Update notification emails to be simpler and more high-level, describing the type and meaning of the notification without embedding transaction details.

Requirements:

• Review all notification email templates that currently include transaction lists or detailed transaction data.
• Simplify email bodies to:
  • Describe the event type and what it means (e.g., “You have transactions ready to execute”, “Some transactions have expired”).
  • Avoid listing individual transaction IDs, amounts, or other sensitive details.
  • Encourage users to open the app to see full details (e.g., “View details in the Hedera Transaction Tool”).
