Feature Issue

User Story

As a user, I want to be able to Mark a contact as untrusted so that so that the next time I enter the chat with this user, I see a note about it that I should be cautious.

Description

How it is done on the Desktop app:

Mark as untrusted option

Untrusted sign

Remove untrusted mark

Acceptance Criteria

1. The new option Mark as untrusted should appear before the option Block user, as shown in the screenshot and in Figma
2. There's a thin line dividing destructive actions, this should be implemented (see in Figma).
3. The new Mark as untrusted option should appear in context menus of any contact, group member, etc. All places where Block user appears.
4. After pressing on Mark as untrusted, the bottom sheet in Figma should be displayed. See also screenshot
5. Similarly to the desktop client, the option Remove untrusted mark should appear when any contact is currently marked as untrusted. The same icon with an exclamation mark should be used.
