feat(node): accept a device link request before the proof (MNP 6.3)

A new device of a known account holds no identity the node pinned, so it
cannot complete a handshake until a pinned device approves it: it now files
device_add_request in the pre-proof window, as the desktop app's case
already required. The request stays inert until countersigned; at most 10
are pending per account, the oldest dropped. A 6.2 node answers it
"Handshake required", which a client reads as "cannot link here".
