[Feature Request] Add WYSIWYG Editor + Code Block Support in Ticket Replies

[nuffsaid]

Hi Folks ,

I'd like to propose a feature enhancement for the support ticket system , specifically, the addition of a **WYSIWYG (Rich Text) editor** in the ticket reply area.

Currently, ticket replies only support plain text or raw HTML. While this works, it's not very user-friendly, especially for staff who want to format their responses without manually writing HTML.

Suggested improvements:

• Add a toggleable WYSIWYG (Rich Text) editor for ticket replies
• Support basic formatting options (bold, italic, lists, links, etc.)
• Add a dedicated [*code*] block or syntax-highlighted area to share code snippets clearly
• Allow switching between Visual and Source (HTML) modes

This is particularly helpful for hosting providers and developers who regularly need to send formatted replies or code samples to clients (e.g. PHP, shell commands, config files).

Bonus: Since HostBill already uses WYSIWYG editors (such as TinyMCE) in other areas like email templates and documentation, it shouldn't be overly complex to integrate the same editor into the support ticket module.

This would significantly improve productivity and professionalism in customer support interactions.
