DxFeed connections keep their real token lifetime

DxFeed connections under Import were sometimes marked Expired and asked for Reconnect even though Volumetrica still accepted the session. Deltalytix had been applying a locally guessed 12-hour expiry to opaque tokens.

New connections now authenticate against Volumetrica's documented v2 API, store the provider-supplied expiration, and reuse the dedicated report token for sync. Existing connections that were saved with the old guessed timestamp stay active until DxFeed returns a real authorization failure. JWT expiry and explicit 401/403 responses still mark a connection expired when the provider actually rejects it.

If you sync evaluation accounts through DxFeed, you should see fewer unnecessary daily reconnect prompts and more reliable automatic sync eligibility.
