fix: improve Docker configuration and documentation

- Change Python path defaults to Docker paths (/data/state, /out)
- Remove STATE_DIR/OUT_DIR from Dockerfile ENV (Python defaults now correct)
- Remove REPEATER_FETCH_ACL feature (unsupported)
- Fix nginx tmpfs permissions with uid=101,gid=101
- Remove Ofelia [global] save=true (caused config parse error)
- Switch to bind mounts for ./out instead of named volume
- Comment out devices section (not available on macOS Docker)
- Add TCP and BLE transport options to meshcore.conf.example
- Document correct macOS socat command for serial-over-TCP
- Update README with macOS Docker workaround instructions
