Fix reauth error and exception in ista EcoTrend integration

[tr4nt0r]

Proposed change

This fixes a problem were the integration initiates a reauth flow every few days. The library handles expiration of the authorization token, but does not handle expiration of the refresh token properly. Although a login is quite costly as it requires several requests, the integrations interval is 24h, so it is justifiable to initiate a re-login on every coordinator update.

This also fixes an error in the translation placeholder were the email account property of the library is accessed that is no longer available since the last dependency update. Instead the value is now retrieved from the config entry.

Could this fix be considered next HA patch version 2024.7.3
