[client] Remove peer deletion on lazy activity detection

Updated WireGuard dependency with a patch and removed the RemovePeer
call on lazy activity detection to force a new handshake initiation
to the updated endpoint. This also flushed the staged queue, dropping
the first packet.

Since UpdatePeer (called after ICE/relay negotiation) triggers
SendStagedPackets via IpcSet/handlePostConfig, the peer removal is
no longer necessary. The staged packet survives and the handshake
is initiated on the real endpoint automatically.

This also eliminates the transient state where the peer's endpoint
and routes were absent between the lazy idle and connected states.
