Add translation support for form titles

### Description

The Web Forms currently translates question labels, options, hints, and constraint messages into the user's selected language. However, the form title remains untranslated, which can hinder user recognition and context before they begin filling out the form.

Translating the form title will:

- Improve user experience by making forms immediately recognizable in the user's language.
- Provide better context about the form's purpose or topic.


Maybe:

| form_title::English | form_title::Spanish | form_id | version | default_language
| -- | -- | -- | --| --|
| Farm Survey | Encuesta agrícola | 12345 | 20150101 | English

Start by tracing how Web Forms currently translates question labels, options, hints, and constraint messages, then identify where the form title and its language variants would enter the existing data flow. Define the required API data and behavior before implementation; done means the title is shown in the user's selected language, with suitable coverage for supported languages.
