The protbot sent "DSGN:\x00" as the sign request type, but the server strips the last 3 characters as a version suffix. Send "DSGN:041" (ZZ client mode 41) to match the real client format. The entrance channel entry parser read 14 bytes for remaining fields but the server writes 18 bytes (9 uint16, not 7), causing a panic when parsing the server list. The channel server panicked on disconnect when a session had no decompressed save data (e.g. protbot or early client disconnect). Guard Save() against nil decompSave. Also fix docker-compose volume mount for Postgres 18 which changed its data directory layout.
