Release Notes: v4.0.5

✨ New Features

KOReader Sync & Progress:
- KOReader Progress: The web reader and book details page now display reading progress from KOReader (if available).
- Resume Playback: If you have progress in KOReader but no web-reader progress, the web reader will now intelligently resume from your KOReader position.
Send-to-eReader Controls:
- Per-User Customization: Added a new setting in user profiles (/me) to toggle the "Send to eReader" modal.
- Direct Send: Users can now disable the modal to trigger an immediate "direct send" to all configured device addresses.
- Admin Control: Admins can manage this setting for other users via the user edit page.
EPUB Fixer UI:
- Single-Book Fixer: You can now run the EPUB fixer on a specific book directly from the UI.
- Live Progress: The page now reloads to show progress immediately, and you can cancel stuck runs.

Cover Handling & Stability:
- Download Limits: Added a configurable size limit (default 15MB) for cover downloads to prevent the server from hanging on massive images (Fixes #1018).
- Optimized Processing: The system now skips ImageMagick conversion if the cover is already a valid JPEG, saving CPU resources.
Metadata Management:
- Bulk Edit Enforcement: Editing books via the "List View" (bulk edit) now correctly marks metadata as "dirty," forcing the system to write changes (Series, Tags, etc.) into the actual EPUB files (Fixes #998).
Startup Robustness:
- Network Shares: Improved startup logic for libraries on network shares (NFS/SMB). The system now gracefully handles "disk I/O errors" by disabling WAL mode and redirecting to the DB config page instead of crashing with a 500 error.
- Ingest Directory: Added a preflight check to ensure the /cwa-book-ingest directory is writable. If permissions are wrong, the upload now fails fast with a clear error message instead of failing silently (Fixes #995).

Kobo & Sync:
- Sync Crash: Fixed a crash caused by books missing date_added or timestamp fields during Kobo sync (Fixes #1011).
- KOReader Malformed Responses: Hardened the sync plugin against malformed responses from the server to prevent KOReader crashes (Fixes #1003).
- Header Auth: Allowed header-based authentication for the kosync endpoint.
UI & Styling:
- Delete Button: Fixed the delete button in the book details toolbar (Fixes #1000).
- Mobile View: Fixed styling issues on the new book details page for mobile devices.
- Login Page: Polished the login page styling.
- Duplicates Sidebar: Fixed a bug where the "Duplicates" sidebar link would re-appear after every restart. The migration now runs only once (Fixes #1010).
Kindle EPUB Fixer: Fixed an issue where the fixer would duplicate XML declarations in files that lacked encoding information.

CI Permissions: Fixed permissions issues in the test pipeline by dynamically setting UID/GID for test containers.
Python Babel: Switched translation scripts to use python -m babel to avoid issues with broken virtual environment shebangs.
Directory Ownership: Improved how the initialization script parses dirs.json to ensure all required folders (including /cwa-book-ingest) have correct ownership.
