configs.retiolum: log tincr reachability, meta-connection and UDP path changes
RUST_LOG=tinc=warn hid every routing/relay event, so path problems were
only visible over SSH. Enable Info for tincd::graph (became
reachable/unreachable via X), tincd::conn (meta connections up/down) and
tincd::net (key exchange, UDP idle revalidation/timeouts, PMTU
fixed/increase/decrease). Their Debug/Trace stays off because tincd::net
and tincd::proto log per packet there; tincd (autoconnect), tincd::auth
and tincd::proto Info stay off as redundant.
Expected volume is roughly 100-250 lines/h on a hub like neoprism and
30-60/h on leaves, plus autoconnect dial attempts to dead hosts in conn.
