Add an option to manually set the text direction (LTR or RTL) when adding a language

[edbond88]

Problem

Text direction (LTR/RTL) for languages is currently hardcoded in the platform. We use language codes that are not included in the predefined RTL list. Because of that, translations are rendered incorrectly - text fields display content in the wrong direction, making it impossible to edit.

Proposal

Add an option to manually set text direction (LTR or RTL) when adding a language, for example, using a checkbox or dropdown.

Expected benefits

• Proper support for custom/non-standard language codes
• Correct rendering in input and text fields
• Ability to edit RTL translations without relying on hardcoded language tags
