Use .gl for Anna's Archive; add manual-import test

Replace default Anna's Archive base URL from https://annas-archive.li to https://annas-archive.gl across docs, UI components, API routes, processors, services, and tests. Add comprehensive tests for the admin manual-import API route and enhance the manual-import route to fetch missing ASIN details from Audnexus and create audiobook records with proper error handling and logging. Update related test expectations and FlareSolverr test usages to reflect the new default URL.
