Allow to edit certain users with two meetings

[reiterl]

Resolve #3841

Only participant detail view.
Needs: OpenSlides/openslides-backend#2576

In the participant detail view it is checked by the get_user_editable presenter, if the operator can edit standard personal info fields. The fields are enabled then.

If Ann (the admin) is not allowed to edit the personal information and Ben (the edited user) has a gender selected then Ann cannot edit the Meeting specific information. I tested all personal information, the gender is the only attribute, which is doing that.

payload:

[
  {
    "action": "user.update",
    "data": [
      {
        "id": 3,
        "gender_id": 3,
        "meeting_id": 2,
        "vote_delegated_to_id": null,
        "vote_delegations_from_ids": [],
        "group_ids": [
          8,
          9
        ]
      }
    ]
  }
]

I cannot reproduce the problem.
I tried:

1. create two meetings MA and MB
2. create a gender G
3. create an participant P1 who is in MA and MB with G
4. create an meeting admin P2 in MA.
5. Login as P2
6. Move into MA, and try to change the group (meeting setting) of P1.
   => It works without problems.

@Elblinator can you give more info?

[Elblinator]

What I did:

1. make run-dev (meaning you have a meeting with A and B both as delegates)
2. login as admin
3. create new committee
4. create new meeting in thenew committee
5. Add (already existing users) A as admin and B
6. Login as A and try editing B
7. The personal information mask is not disabled and you cannot edit only the meeting specific information

I just realised that the personal information mask is not correctly displayed there as well, I can imagine that this is the actual bug. The personal information mask is not disabled

Okay, ty, I see the problem. I can reproduce the problem in main, too.

[reiterl]

These are two cases:
A) 1 committee with 2 meetings
B) 2 committees with 1 meeting each
The B) case doesn't work as excepted and was wrong in main too. I will look at it.

I have talked to @hjanott , I want to ask for the editable fields with one presenter call. So there needs to be improvements.

[reiterl]

Added a version which uses the new get-user-editable fields presenter. This part of the code works.
But I see a flickering Save button in the edit form. I will try to find the reason for this.

Use an actual check if the data is loaded.

[Elblinator]

The personal information fields are disabled too much:
all Scenarios are scenarios where the fields should be enabled:

• There are two committees A and B

• Committee A has meeting A1 and A2, A3

• Committee B has meeting B1 and B2

• And more

• "A" is Meeting A1 with user.can update rights and in A2, B1 and B2 as admin and they are in different meetings from different committees without these rights

• "B" is in meeting A1 and A2 as deli/default

• "C" in meeting A1 and B1 as deli/default

• "D" in meeting A1, A2 and B1 as deli/default
