- Rename is_admin/admin_mode -> is_cheat/cheat_mode (only FUN_* event
triggers are cheat params, not operational commands like SCRAM)
- Fix steam ejector valve write commands: int 0-100, not bool
- Move SCRAM, EMERGENCY_STOP, bay hatches, turbine trip etc. to normal
write-only (not cheat-gated)
- Add FUN_IS_ENABLED to readable params (it appears in GET list)
- Add get_valve/get_valves, open/close/off_valve(s) methods with correct
actuator semantics: OPEN/CLOSE powers motor, OFF holds position
