The reporting menus for Planning, Field Service, and Project timesheet planning now show clearer helper messages. This helps users better understand what each report is for and how to use it when navigating service-related reporting areas.

Mass mailing templates were cleaned so preview screens better reflect the intended email content. Decorative images no longer show unnecessary alternative text, reducing visual clutter and making previews clearer for users preparing campaigns.

Purpose
=======
Clean the mass mailing templates to have a better preview.
(e.g. Remove the alt attribute of the images which are not
part of the mail content)
