## Summary * **What is the goal of this PR?** (e.g., Fixes a bug in the user authentication module, Display the book cover image in the **"Continue Reading"** card on the home screen, with fast navigation using framebuffer caching. * **What changes are included?** - Display book cover image in the "Continue Reading" card on home screen - Load cover from cached BMP (same as sleep screen cover) - Add framebuffer store/restore functions (`copyStoredBwBuffer`, `freeStoredBwBuffer`) for fast navigation after initial render - Fix `drawBitmap` scaling bug: apply scale to offset only, not to base coordinates - Add white text boxes behind title/author/continue reading label for readability on cover - Support both EPUB and XTC file cover images - Increase HomeActivity task stack size from 2048 to 4096 for cover image rendering ## Additional Context * Add any other information that might be helpful for the reviewer (e.g., performance implications, potential risks, specific areas to focus on). - Performance: First render loads cover from SD card (~800ms), subsequent navigation uses cached framebuffer (~instant) - Memory: Framebuffer cache uses ~48KB (6 chunks × 8KB) while on home screen, freed on exit - Fallback: If cover image is not available, falls back to standard text-only display - The `drawBitmap` fix corrects a bug where screenY = (y + offset) scale was incorrectly scaling the base coordinates. Now correctly uses screenY = y + (offset scale)
