Add per-link MTU support to Transport trait

Browse Source 
Add link_mtu(&TransportAddr) method to the Transport trait with a
default implementation that falls back to the transport-wide mtu().
This enables transports like BLE to report per-connection MTU values
while maintaining backward compatibility for UDP and other transports
that use a single MTU for all links.

Update the forwarding and session send paths to query link_mtu() with
the next-hop peer's current address, falling back to transport-wide
mtu() when no address is available.
