Fix: Live Data Sensors Showing Unavailable Every 10 Minutes

The PVS firmware closes the WebSocket connection every 10 minutes as a hard session limit, then accepts a new connection within a few seconds. Each time this happened, live data sensors briefly showed unavailable in the history graph before reconnecting. With frequent polling enabled, this created a visible gap or dip every 10 minutes throughout the day.

Live data sensors now hold their last known value for up to 150 seconds when the WebSocket disconnects, instead of immediately going unavailable. The 10-minute firmware session cycle reconnects in 2-6 seconds, which is well within the hold window, so those transitions are now invisible in the history graph.

PVS reboots take longer (typically 8-10 minutes) and will still appear as an unavailable gap after the 150-second hold expires. This is intentional: a reboot is a meaningful outage worth seeing in the history, while a routine 2-6 second firmware reconnect is not.

Update via HACS or manual file copy and restart Home Assistant.
