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.
