bind composite discovery and add emulated POS895

Browse Source 
Epson printers answer ENPC and POS895/POS896 answer SPRT; only the
composite discovery service sees both. Wire CompositeDiscoveryService
(wrapping DiscoveryService + SprtDiscoveryService) into production DI,
and add a 576px emulated POS895 (127.0.0.4) alongside the existing
TM-U220II/TM-T30III emulation entries so receipt layouts can be
checked without hardware.
