Add *.home.arpa / in-addr.arpa / ip6.arpa rules to ctrld TOML

Browse Source 
ctrld was only forwarding *.lan and *.local to Unbound.
Reverse DNS (PTR) queries and RFC 8375 *.home.arpa names were
leaking upstream instead of being answered by Unbound locally.

Both router-mode and proxy-mode TOML rule blocks now include:
  *.home.arpa  → upstream.local
  *.in-addr.arpa → upstream.local   (IPv4 reverse DNS)
  *.ip6.arpa   → upstream.local    (IPv6 reverse DNS)

This ensures all local/private DNS resolves correctly after reboot
without any manual intervention or unknown/broken state.
