Currently, Robrix unconditionally shows the message input bar at the bottom of the RoomScreen. This ignores the fact that the current logged-in user may not have sufficient permissions (power levels) to actually successfully send a message to that room.
Desired behavior
Instead, Robrix should show a different view component there (in place of the message input bar) when the user is viewing a room that they do not have permissions to send a message in.
Implementation ideas
We can use the Room:can_user_send_message() to determine whether the user is allowed to send a message in the current room. If that returns false, we should hide that message input bar and instead display a notice informing the user that they are not allowed to send messages to this room.
This should be checked (at a minimum) every time the user opens the room. An even better implementation would be to:
upon the user opening the room, we subscribe to room state changes such that we can be notified if the user's permissions changes such that they can or cannot send a message to the room.
upon the user closing the room, unsubscribe from said state changes.
