Implement language switches for titles of plays

[lehkost]

After implementing dracor-org/dracor-api#118 we could start implementing a language switch for titles of plays. Language codes should be delievered by the API and could then result in a switch button on corpus overview pages and pages for single plays.

If my assumption in dracor-org/dracor-api#118 (comment) is right then I would assume that this language switch would toggle between original language and English. Thus it would only make sense for non-English corpora and only if a non-English corpus has a significant number of translated titles and names.

And this toggle would then have to make clear that it only translates play titles (and possibly author names), but not the entire interface. Maybe it could be something like a checkbox with the label "Display English titles" (or maybe "Prefer English titles and names" as a site-wide preference).

In the corpus overviews, I would add a small "EN" button in both the "Authors" and "Title" column headers to switch to English author names and play titles. This way, it would be visually clear, that only these two columns are affected.

It's harder to decide where to place that "EN" button in the single-play view. On these pages we should also offer a switch to change to display English character names if available (for both the network and the character list to the right).

@lehkost is it really necessary to toggle the language on page or even column basis. It would be easier to implement this as a side wide setting with a single toggle for instance in the top navigation (maybe with a little gear icon and a menu item "Prefer English names and titles"). I think it would be more clear that this does not translate the site consistently but provides English titles only where they are available. Also, a central toggle would scale better should we decide to add more languages.

Yes, that's true – a side-wide toggle is better. We could probably describe it as "Show metadata of plays in English if available", and could detail it, if that helps to understand what the function does, to apply to "authors, titles, character names".
