summary: include filter chain counters via chain_summary()
netcfg/summary now threads the FilterTable through and calls
chain_summary() — surface per-chain packet/byte/policy counters.
Output now includes:
filter chains:
input: pkts=12 bytes=5678 policy=ACCEPT
output: pkts=0 bytes=0 policy=ACCEPT
forward: pkts=0 bytes=0 policy=ACCEPT
prerouting: pkts=0 bytes=0 policy=ACCEPT
postrouting: pkts=0 bytes=0 policy=ACCEPT
NetCfgScheme::new gains filter_table: Rc<RefCell<FilterTable>> param.
Smolnetd passes the existing filter_table Rc.
All 5 unit tests still pass — refactor preserves behavior.
