Move away from abandoned dependencies

[tomudding]

Current behaviour

Package laminas/laminas-crypt is abandoned, you should avoid using it. No replacement was suggested.
Package laminas/laminas-mail is abandoned, you should avoid using it. Use symfony/mailer instead.

Desired behaviour

laminas/laminas-mail is replaced with symfony/mailer and laminas/laminas-crypt is removed and the existing code is changed to remove its functionality (see https://github.com/search?q=repo%3AGEWIS%2Fgewisdb+%22Laminas%5CCrypt%22&type=code)

This should be done before we start using Composer 2.7, as at that point, the behaviour of accepting/reporting abandoned packages will change.
