fix: persist config_runtime.yaml inside volume-mounted memory dir

config_runtime.yaml was written to the container root (/) because the path
resolved via Path(__file__).parent.parent from /app/config_manager.py = /.
This location is not volume-mounted, so all runtime config changes (language,
debug flags, Cheshire Cat toggle, mood, GPU preference) were lost on every
container restart.

Moved runtime_config_path to memory/config_runtime.yaml, which lives inside
the volume-mounted ./bot/memory:/app/memory directory and persists across
restarts. Also reordered __init__ so memory_dir is initialized before
runtime_config_path depends on it.
