Fixes #4765 – Missing FieldCell wrapper in Customer Portal Process Ticket templates

This PR addresses a UI issue in the Customer Portal of OTOBO when using Process Tickets with active Activity Dialogs.

Problem

The input fields for built-in fields (like Title, Queue, Service, etc.) do not show the floating labels correctly, because the required FieldCell wrapper <div> is missing in the templates.

This only affects Customer Portal process tickets, not the agent interface.

Dynamic fields are not affected, as their templates already include the correct FieldCell container.

Solution

The following template files were updated to include the missing wrapper:

• CustomerArticle.tt
• CustomerPriority.tt
• CustomerQueue.tt
• CustomerService.tt
• CustomerSLA.tt
• CustomerState.tt
• CustomerTitle.tt
• CustomerType.tt

Each input field is now correctly wrapped inside:

<div class="FieldCell">
    <div class="Field">
        <input ... />
    </div>
</div>
