feat(reader): wire up reading progress save and restore

The web reader had all the infrastructure for progress persistence (updateReadingProgress/getReadingProgress API functions, PUT/GET endpoints, database queries) but the reader.ts never called them. Changes: - Add debounced (2s) saveProgress call on every relocate event that PUTs percentage, current_page, total_pages, and epubcfi to the existing /api/media-items/:id/progress endpoint - Replace renderer.next() with view.init({ lastLocation }) to restore the reader to the last saved position on load (CFI first, then fraction fallback, then default first page) - Pass savedPercentage and savedCfi from server-side progress data through readerInitExpr config to the JS initReader function - Add mediaItemId and saveTimeout to the Alpine data object This fixes both the blank /progress page and the missing progress section on book detail pages — both were empty because the reading_progress table never received any data from the web reader.
