"whole known network" which is what public timeline used to be

Only domain blocks with suspend severity will block PuSH subscriptions
Silenced accounts should not appear in conversations unless followed

So that if we get an error, then we will
only delete status if it is an 404 error

Moved validation to services/post_status_service.rb

Modified uploadCompose action to send media ids of attached
media when sending a request. Modified create method in MediaController
to check if when posting a video, there are no other media attached
to the status by looking at the media ids sent from the uploadCompose
action.

No need to flash error message when status is not found.
The column will display the message "status not found"

The status is not showing anymore after clicking on it
