The reader's saveProgress() now sends a more complete payload to the
backend so ProgressService has more data for enrichment and merge:
- chapter: computed from TOC boundary index instead of missing
- reading_mode: current display mode (page, chapter, percent, time-left)
- zoom_level: for fixed-layout books (renderer.zoomPercent / 100)
- current_page: real page number for fixed-layout, location.current for
reflowable
- total_pages: section count for fixed-layout, location.total for
reflowable
Adds computeChapterPageBoundaries(doc) for reflowable EPUBs that maps
TOC anchors to rendered page numbers, recomputes after fonts load.
Adds computeFixedLayoutChapterBoundaries() for fixed-layout books that
resolves TOC hrefs to page indices via view.resolveNavigation().
Updates reader.templ to expose isFixedLayout to Alpine init.
