cs16-dm-server: CS 1.6 deathmatch server in Docker

One-command setup (SteamCMD + pinned, checksum-verified ReHLDS / ReGameDLL /
Metamod-R / AMXX / ReAPI / ReUnion / CSDM-ReAPI / YaPB / GunGame), .env
settings, ./cs menu (map, DM/GunGame mode, bots, kill counter, restart,
update), own plugins (extras, rtv, mode switch), all-time kill counter,
watchdog + nightly backup, docs for admins and players.
