Fix xxxtik empty results; replay solved identity on raw requests

Raw requester calls did not adopt the remembered FlareSolverr user agent,
so a RedGifs token minted under it was rejected on every gif lookup.
Tag/creator pages that mix non-RedGifs sources are refilled from later
cursor batches instead of coming back empty.
