sysopsandClaude Sonnet 5 1539c589a1 Normalize AllocatedIPs/ExtraAllowedIPs to network address before ip route replace
A client CIDR with nonzero host bits (e.g. 10.66.120.1/30 instead of the
network 10.66.120.0/30) is tolerated by wg's own AllowedIPs/setconf, which
just warns, but plain iproute2 rejects it with "Invalid prefix for given
prefix length" and aborts the whole PostUp chain, taking the interface
down on start. Added a routeNet template func that clears host bits via
net.ParseCIDR before generating each PostUp route line.

# Table is forced to "off" and routes are (re)installed explicitly below via
# `ip route replace` instead of letting wg-quick manage them with `ip route
# add`. Multiple servers on this box can legitimately share an overlapping
# AllowedIPs entry (e.g. the same /32 reachable via more than one tunnel);
# wg-quick's own route handling hard-fails the whole interface with
# "RTNETLINK: File exists" the moment two servers claim the same route,
# which used to take down every server started after the first. `replace`
# is idempotent and never fails on a pre-existing route.
