Implement agenda item forwarding

[luisa-beerboom]

Closes #5281

To run this, ensure OpenSlides/openslides-backend#3144 is checked out and lib/openslides-go is updated according to OpenSlides/openslides-meta#318 (the latter can be found in luisa-beerboom/openslides-go branch name b-3075-agenda-forward)

[Elblinator]

• "More"/"Less" is closing the list from the "Forward motion to"/"Receive motions from"
• Add a snack bar for succesful forwarding like in the motion forward
• this is missing: "If you try to forward something else than a topic a warn text should be display" sth like "Warning: You are trying to forward something else than a topic, only the topic will be forwarded" and the id from the not topic should be excluded from the payload"
• please put the new permisson directly over agenda.can_manage
• topic detail -> person who should be able to forward w minimal permission (agenda.can_see, agenda.can_see_internal and agenda.can_forward) cannot see the three dor menu, hence the option to forward
• list view a participant with minimal permissions cannot see the forward option

still needs testing from @bspekker etc.

The dialog needs some margin is needed after the warnings befor the Los selections. The warnings could also be in a smaller font size.

Some wording suggestions:
Helptext for permission:

Can forward agenda items to other meetings within the OpenSlides instance.

Further requirements:
1. forwarding hierarchy must be set at the organiztional level in the committee.
2. target meeting must be created.

Wording of helptext for Los in dialog:

This will add participants, structure levels and groups to the target meeting(s)

Wording of warnings in dialog:

Warning: You are trying to forward something else than a topic, it will be skipped and not forwarded.

Warning: You are trying to forward a parent agenda item without at least one of its children. Children will not be automatically forwarded alongside their parent items.
