Introduce file and directory permission settings (fileChmod, dirChmod) end-to-end. UI: new controls in Paths settings with octal validation and defaults (664/775). API: GET exposes defaults; PUT validates octal strings and upserts configuration keys (file_chmod, dir_chmod) and clears related cache keys. Runtime: read config values in file utilities and services (FileOrganizer, direct-download, chapter-merger, epub-fixer) to apply mkdir modes and chmod files/dirs; FileOrganizer now accepts fileMode/dirMode and getFileOrganizer reads/parses DB settings. Docker: add UMASK option to docker-compose and propagate/apply UMASK in entrypoint/app-start scripts. Tests: update mocks to account for config service usage.
Introduce an optional Kindle EPUB compatibility fixer and integrate it into the ebook organization flow. Adds a new config key (ebook_kindle_fix_enabled, default false), a settings API update, and a UI toggle (visible when preferred format is EPUB). Implements src/lib/utils/epub-fixer.ts (uses adm-zip and cheerio) to apply fixes: add UTF-8 XML declarations, remove body/#bodymatter fragments from links, validate/normalize dc:language, and remove stray <img> tags without src. organize-files.processor now detects EPUB downloads, runs the fixer (produces a temp fixed EPUB), uses the fixed file for organization, logs fixes, and cleans up temporary files; fix failures are non-blocking and the original download is preserved. Adds dependencies adm-zip and @types/adm-zip and updates documentation and types/UI to expose the new setting. Also includes helper functions to detect EPUB paths in downloads.
