Zeedif	595608bd62	feat: Implement KOReader Progress Synchronization (#1770 ) * feat(sync): implement KOReader progress synchronization This commit introduces a comprehensive feature to synchronize reading progress with a KOReader sync server. It includes a compatibility layer to handle discrepancies between Readest's CFI-based progress and KOReader's XPointer/page-based progress, primarily using the `percentage` field as a common ground. Key additions include: - A new settings panel under "KOReader Sync" for server configuration, authentication, and sync strategy management (e.g., prompt on conflict, always use latest). - A conflict resolution dialog that appears when remote progress differs significantly from local progress, allowing the user to choose which version to keep. - A client-side `useKOSync` hook to manage the entire synchronization lifecycle, including API calls, state management, and conflict resolution logic. - A new API endpoint `/api/kosync` that acts as a secure proxy to the user-configured KOReader sync server, handling authentication and forwarding requests. - Logic to differentiate between paginated (PDF/CBZ) and reflowable (EPUB) formats, using page numbers for paginated files where possible and falling back to percentage for reliability. - Spanish translations for all UI elements related to the KOReader sync feature. - Addition of `uuid` package to generate a unique `device_id` for sync purposes. Refactor: - The `debounce` utility has been improved to include `flush` and `cancel` methods, allowing for more precise control over debounced function execution, which is now used in the sync hook. * fix(kosync): add support for converting between XPointer and CFI in progress synchronization * fix(kosync): update navigation method to use select instead of goTo for paginated formats * fix(kosync): refactor synchronization settings and improve conflict resolution handling * fix(kosync): add event dispatcher for flushing KOReader synchronization * fix(sync): handle xpointer in a different section, fix styling * i18n: update translations --------- Co-authored-by: Huang Xin <chrox.huang@gmail.com>	2025-08-11 17:53:28 +02:00
