Added #15803: Category Field to Asset Related Mails

[NebelKreis]

Description

This pull request introduces the Category field to the emails generated for asset Check-in, Check-out, Acceptance, Decline and Requests. Previously, these emails included asset details like model and tag, but without the category, it was sometimes difficult to identify the type of asset. By including the category, the emails provide clearer and more actionable information.

Key-Changes:

• Added the Category field to the templates of:
  • Check-in emails
  • Check-out emails
  • Asset acceptance/decline emails
  • Request confirmation emails
• Adjusted the email generation logic to pull and include the category from the database.

Fixes #15803

PR Summary

• Enhancement in Asset Information Display
