Salutation Field should have a higher character cap

Is your feature request related to a problem? Please describe.
German salutations can get long when theres no additional "title" field for profiles. For example, a normal salutation in german could be "Herr Prof. Dr. rer. nat.", which is way beyond the char(10) cap.

Describe the solution you'd like
The field should allow more characters than 10, ideally something around 30 should be OK.

Describe alternatives you've considered
There could also be a seperate field for the "title", like "Prof. Dr.", so theres a difference between salutation and title. They both should be integrateable in the e-mail templates.

Additional context
There's also no mention about this cap in the janeway documentation (if I just happen to not find it, please do tell) and I think that should be added. We stumbled across this issue by testing the import feature.

No file or test is named. Start by locating the salutation field and the import path, then check how the value is exposed to email templates. Done means the field accepts longer salutations, imports handle them correctly, and the character cap is documented.
