[Channel Permissions] Hide reactions from community users that don't have the permission to add reactions

[alexjba]

Description

Design When a new channel is created and permissions are added, there is an option to allow community members with view only permission to add reactions.

This means the reactions should only be visible to the members with the following permissions:

1. View and post permission
2. View and add reaction permission

TODO:

• [x] Integrate the backend flows in nim (https://github.com/status-im/status-desktop/issues/13292)

• [x] Remove this commented flag that's hiding the option https://github.com/status-im/status-desktop/blob/master/ui/app/AppLayouts/Communities/views/PermissionsView.qml#L132

• [x] Implement setViewOnlyCanAddReaction https://github.com/status-im/status-desktop/blob/master/ui/imports/shared/stores/PermissionsStore.qml#L20

• [x] Provide the ViewOnlyCanAddReaction value in the store and connect it to the CreateChannelPopup.viewOnlyCanAddReaction

• [x] Update the MessageView.d.addReactionAllowed with the backend value for the user https://github.com/status-im/status-desktop/blob/master/ui/imports/shared/views/chat/MessageView.qml#L264
