fix(wireguard): remove memoization from config_contents and hosts_contents

Stale external changes to wg1.conf or /etc/hosts were invisible because
LocalWireGuard cached the first read forever. Remove the cache entirely
so every operation sees the current file state. Also removed the now-unnecessary
ivar updates after write_config/write_hosts.
