Read imported thesis position history

Requires Privy bearer authentication. Reads prepared external Fomo/Pump thesis results through the authenticated indexer SocialQuery service; never fetches Codex history on the request. The event_id is the backend public thesis UUID, not the provider post ID. Rechecks current post/profile visibility and provider wallet association on every page. Initial supported coverage is unambiguous non-native Solana wallet/token positions. Current status older than five minutes becomes unknown while previously observed closed cycles remain. Cursors are opaque, bound to this thesis and the observation revision; a changed revision returns 400 and the client must restart without a cursor. An unavailable or older indexer without this RPC returns 503, never an empty successful history. Results are gross provider estimates with unavailable fees and must not authorize portfolios or trading. request_status distinguishes pending acquisition, retry scheduling, available observations, and terminal unavailable results. This GET never creates or prioritizes work.
