Reduce trigger functions for equal fields

To reduce them we have two approaches. Either combining them with parameter adjustment and logic changes or removing/altering such fields.
The latter can be done for:

• option/content_object_id : user/option_id (Here we would need to reference meeting_user instead and would get rid of two functions)
• projection/content_object_id : meeting/projection_ids (Here we would need to add an in-between model like welcome_card.)

Start by locating the trigger functions associated with option/content_object_id and projection/content_object_id, then trace their references to user/option_id, meeting_user, meeting/projection_ids, and the proposed welcome_card model. The issue needs a design decision between combining functions and altering fields; done requires an agreed approach and confirmation that the redundant trigger functions can be removed or consolidated.
