wg-quick's own AllowedIPs route handling does a plain `ip route add` per entry into the main table and hard-fails the whole interface bring-up with "RTNETLINK: File exists" the moment two servers share an overlapping AllowedIPs entry (real case: a client's transit IP duplicated across 4 imported servers). Set Table = off and generate `ip route replace` PostUp commands instead - idempotent, never fails on a pre-existing route, and multiple servers can coexist even when their peers' AllowedIPs overlap. Also make ServerServiceRestart write the config to disk first, same as ServerServiceStart already does - it had the same "config file missing" failure mode.
