v5.0.0

• Added: signal-level indicator (kran_signal_entity) next to the battery indicator.
• Added: disable_animations — turns off every animation except the crane-toggle motion.
• Added: card_height / card_min_height.
• Changed: leak sensors are now an unlimited leak_sensors: [{ label, entity }, ...] list (editor currently shows up to 2 rows via a "+ Add leak sensor" button).
• Added: automatic migration from the old bathroom_*/kitchen_* fields into leak_sensors on load — no config lost on upgrade.
• See README changelog for full details.
