Fix read receipts being overwritten by delivery ACKs

Browse Source 
- Added logic to prevent downgrading from 'read' status to 'delivered'
- When an ACK arrives after a read receipt, the read status is preserved
- This fixes the issue where blue checkmarks briefly appear then revert to green
- Applied fix to all message types (main, private, room)
