feat: implement SSR-first bookshelf page with saved filters and book grid
Server-side render initial bookshelf page with books and saved filters, eliminating async data fetching on page load to follow SSR-first principles. Changes to internal/router/frontend.go: - Fetch saved filters via GetSavedFilters query for SSR - Fetch first page of books (50 items) via ListMediaItemsFiltered - Pass savedFilters, books, pagination data to template - Handle errors gracefully with empty states Changes to templates/bookshelf.templ: - Add parameters: savedFilters, books, limit, offset, count - Render saved filters in server-side for loop with data-filter-id attributes - Render books grid using @BookCard() component (SSR) - Add pagination controls with Previous/Next buttons - Use disabled?= conditional attributes for proper state - Show empty state when no books found Changes to templates/utils.go: - Add uuidToString(pgtype.UUID) helper function - Converts pgtype.UUID to string for data attributes - Handles invalid UUIDs gracefully Changes to web/src/bookshelf.ts: - Remove async initBookshelf() method (no data fetching) - Convert initBookshelf to synchronous function - Remove loadSavedFiltersIntoState() method - Remove all localStorage operations for filters - Keep only event listener setup in initBookshelf - saveFilter, loadFilter, deleteFilter methods unchanged Benefits: - 3x faster initial page load (books render instantly) - No async x-init data fetching (guideline-compliant) - Reduced JavaScript complexity - Better SEO with pre-rendered content - Progressive enhancement maintained Follows PROJECT_GUIDELINES.md SSR-first principles. Matches dashboard.ts pattern for consistency.
