fix: remove hardcoded /Users/apayne persistence path from standalone game engines

Evennia-local-world simulators previously hardcoded a single machine's
home directory, making them non-portable. WORLD_DIR now reads from
TIMMY_WORLD_DIR environment variable with a sensible default (~/.timmy).

Resolves: #831
