Closes https://github.com/ppy/osu/issues/33465 probably.
This reverts the replay frame de-duplication logic to what it was before
https://github.com/ppy/osu/pull/33148#discussion_r2091549388.
I don't have good reproduction steps. I tried to write a test case for
this that isn't just "press and release a key in the same frame",
thinking that maybe there was some loophole in the osu! touch input
mapper that may produce this situation artificially, but I could not in
many configurations. So I have to assume that this just *can happen*
organically.
When the server requests a disconnect due to a user connecting
via a second device, the client will now log the user out on the first
device and show a notification informing them of the cause of
disconnection.
