[survey_accounts] Translate to Japanese and clean up translation code

[driusan]

This translates the survey_accounts module into Japanese, and in doing so cleans up some portions of the translation code.

1. Close, Email, and Status all exist in the loris namespace, so use those instead of duplicating the translations in the module
2. There was an extra apostrophe in one of the English strings.
3. "already exists for given candidate for visit" was a partial string using string concatenation to add variables, so use an interpolated sprintf string
4. "does not exist for given candidate" was a string concatenation, but the only variable being concatenated was the translation of "Visit" from the loris namespace. So just include "Visit" in the whole string to make it easier to translate the sentence as a whole.
5. While updating the French to match the new template strings, I found "le candidat donné" for "the given candidate" to be an awkward literal translation, so I changed it to "le candidat spécifié". (I can revert this if French speakers disagree.)
