A number of Uwazi system messages aren't translatable

[llfinch]

Describe the bug After performing certain actions in Uwazi, the system generates a message at the top of the screen in a white banner with a green stripe on the left-hand side to update the user on the status of their action, like so:

There are also system messages that come via email, such as when you reset a password.

The vast majority of these messages don't appear to be translatable, neither by Settings --> Translations --> User Interface nor by the Live Translate feature (which would be tricky in any case, as these banner messages disappear after a few seconds and you can't turn on Live Translate in your email inbox).

I've taken note of the messages I could see while traveling through Uwazi that aren't translatable. However, this is not an exhaustive list and I'm sure further investigation is necessary at the code-level to make sure all untranslatable messages are identified, which I am unable to do. See table below.

Expected behavior If I have a non-English-language UI activated on my Uwazi instance, I would expect to also receive validation of my actions or important error messages in my language too.

added to hub. Save your work to make change permanent.	Part of message that appears at the top of the screen when a user adds an entity to a relationship via the righthand sidebar, either through selecting an existing entity via the search bar or creating a new one. The text is preceded by the name of the entity, e.g. "Court Hearing 8/7/1992 added to hub. Save your work to make change permanet."
