It's more convenient to manage notification channels separately, as it
is done with email settings. Notification hook and other forms are
adopted to only select channels. Hooks can now use more than one
channel.
This is a start to have different kinds of notifications. It is
possible to be notified via e-mail, matrix or gotify. It also extends
the current "periodic query" for due items by allowing notification
over different channels. A "generic periodic query" variant is added
as well.
There are models for Spanish, that have been added now. Also the
Hungarian language has been added to the list of supported
languages (for tesseract mainly, no nlp models)
The upload request can now contain a boolean for importing only
attachments when e-mails are uploaded. This option is now also added
to a source url.

It was wrongly stored using RPeriodicTask directly, but the higher
level `UserTask` must be used instead, because this ensures a
correctly scoped periodic task using the `updateOneTask` method. Since
this is a system task, it can be given a fixed ID which makes it now
safe even if stored using RPeriodicTask directly.
The bug resulted in multiple empty-trash tasks to be inserted (on each
restart).

In order to keep deleted items for a while, the periodic task can now
use a duration to only remove items with a certain age. This can be
used to ensure that a deleted item stays at least X days before it
will be removed from the database.

Classifier don't work on each attachment, but on all. So the results
must not be stored at an attachment. This reverts some previous
changes to put the classifier results for item entities into its own
table.
