RTL language support (e.g. Arabic) is broken in editor view

[eskopp]

When using django-mdeditor with right-to-left (RTL) languages like Arabic, the visual preview works correctly in RTL — but the actual editor (textarea) and line numbers remain left-to-right. This leads to confusing alignment and a broken editing experience.

🔍 Observed behavior

• The preview (.editormd-html-preview) renders RTL correctly ✅
• The editor input (textarea and .CodeMirror) stays LTR ❌
• Line numbers and text do not align with RTL direction ❌
• Toolbar remains LTR — which is correct ✅

✅ Desired behavior

When the language is set to an RTL language (e.g. ar, fa, he, ur), the entire editor area should be rendered with dir="rtl", including:

• Markdown editor input
• Line numbers
• Preview
• Base .editormd wrapper
