v4.3.0

Fixed

• Failed switch/valve service call left the card permanently stuck showing "opening…/closing…" for the full toggle_lock_ms even though nothing happened. Now caught and the state resets immediately.
• An unavailable switch_entity (or one that never existed) rendered as a plain CLOSED state, which is misleading for a shut-off valve. Now shown as a distinct Unavailable state with the action button disabled.

Changed

• The valve now toggles only via the action button — tapping elsewhere on the card body no longer does anything.
• A leak-sensor block is shown whenever its *_leak_entity is set, regardless of the label. *_label now only controls whether the name text is shown.
• With auto_toggle_duration: true, the measured actuator time now fully replaces the manually configured toggle_lock_ms once a measurement exists.

Improved

• The water animation now pauses when the browser tab is hidden or the card scrolls off-screen (visibilitychange + IntersectionObserver), reducing CPU/battery use on always-on dashboard panels.
