Add Space Engineers server support

Integrates Space Engineers dedicated server (docker+wine on 192.168.2.78) into GSM:
- config.json entry with docker runtime and log-based player detection
- getSpaceEngineersPlayers() parses docker logs for connect/disconnect events
- Extends type-check sites in rcon, autoshutdown, discordBot, servers routes
- Frontend ServerCard/ServerDetail logo + address wiring
