Fix IPv6 direct mode routing for LAN clients
- Remove static network_ipv6_gateway from LAN hosts so they pick up
Pi's radvd RA (pref high) instead of FritzBox (pref low)
- Add missing ip6tables FORWARD ACCEPT rule for new connections in
direct mode (only ESTABLISHED was present, blocking new flows)
- Flush ip6tables nat POSTROUTING table on clear instead of fragile
per-rule -D deletion to prevent stale rule accumulation
