Describe the bug
The organizer email input in event creation/edit forms is rendered with the organizer's email as the actual input value (prefilled) instead of being shown as placeholder text. Initially the field was not a placeholder — it contained the email as a value — which exposes the organizer's email and may cause accidental submission or confusion.

What it was before

• The form field was prefilled with the organizer's email as the input value (e.g., <input value="org@mail.com">).
• The email appeared as an actual value rather than as a placeholder/hint.

Steps to reproduce

1. Go to the event creation or edit page as an organizer.
2. Observe the "Organizer email" field on the form.
3. Notice the organizer's email appears as the field value (not as a gray placeholder).
