Summary by cubic

Ensures emails keep the customReplyToEmail when hideOrganizerEmail is enabled, so replies go to the intended address without exposing the organizer. Applies the same reply-to logic across reminders, the workflow service, and the header helper.

• Bug Fixes
  • Use customReplyToEmail when hideOrganizerEmail is true; otherwise fall back to organizer email.
  • Add reply-to only when a value exists.
  • Align logic in scheduleEmailReminders, EmailWorkflowService, and getReplyToHeader.
