🐛 Fixed
- A brief BLUETTI cloud outage no longer sends every entity to unavailable. The cloud drops out for a few seconds at a time - the official app loses the device at the same moment - and one retry inside a poll does not always outlast it. Two failed polls in a row now keep the values already shown, at most 90 s; after that the entities do go unavailable, because by then it is not a blip. A rejected token still goes straight to the sign-in path. Reported with the app screenshots that proved whose side it was on, in #63.
