Introduce per-user configurable home page sections and a unified Audible cache/category model. Adds Prisma models (UserHomeSection, AudibleCacheCategory) and migrations to create tables and remove legacy popular/new_release flags; updates schema.prisma accordingly. Add API routes for user home sections, live Audible categories, and category-based audiobook listing, and refactor popular/new-releases/covers routes to read from AudibleCacheCategory. Frontend: new HomeSection component, HomeSectionConfigModal, useHomeSections hook, and homepage changes to render dynamic sections plus image fallback to a placeholder SVG. Also add placeholder_cover.svg and tests for home sections and the audible refresh processor.
Add support for hiding audiobooks that are already available by introducing a hideAvailable query flag and excluding matching ASINs at the DB level. Implemented getAvailableAsins() in audiobook-matcher to gather ASINs from the library and completed requests, and wired it into the popular and new-releases API routes to apply a notIn filter. Propagated the hideAvailable flag through useAudiobooks so client requests include the parameter, and adjusted the homepage to reset pagination when the flag changes. Replaced two StickyPagination instances with a new UnifiedPagination component (new file) that provides a single context-aware floating paginator which tracks the dominant section and allows switching between Popular and New Releases. Also removed client-side filtering in favor of server-side exclusion and made small imports/cleanup in page.tsx.
Replaces scattered console statements with a unified RMABLogger across backend API routes and services. Adds LOG_LEVEL-based filtering, job-aware database persistence, and context-based logging. Updates documentation to describe the new logging system and usage patterns. Also documents qBittorrent CSRF header fix
