[dashboard/statistics] Translate Recruitment widget

[driusan]

This translates the recruitment widget (the last widget) on the LORIS dashboard, so that the entire dashboard is now translated (The recruitment widget had been waiting on #9937 to be merged before translating it.). Japanese is used as a test language.

It also fixes a regression on the study progression translation introduced by #9937 as new filters that are shared between the two were added.

There are some translations that don't seems to load in my side:

I am not sure where "Pie" and "Bar" come from. They do not seem to be in the code. @skarya22 do you know?

"Participants: xxx" and "Overall Recruitment" should be translated, though. I'll try and look into them and "Unknown". Do we translate the "Loading..." elsewhere in LORIS?

• Yes Pie and Bar seems to came from the library used but myself I'm don' t know.
• I did saw the translations for "Overall Recruitment" in the code but somehow they are not loading for me. If you can retest in your side would be great.
• Regarding "Loading...", I don't think we translated this before... maybe is not super evident in other parts and was evident here because is taking more time... just saying… not sure if we can implement it easily... we can put an image "like a sandglass" or something and we avoid translations.

@racostas I added translations for the missing line graph labels, "Unknown" and "Loading...". I don't think I can do Pie/Bar since it doesn't seem to be coming from our code.

I'm not sure why "Overall Recruitment" isn't translating for you, it is for me. Did you restart the web server after running make dev or make locales to be sure it's not using a cache?

Can you re-test?

LGTM now !
