Library access roles had no effect on metadata editing: only the global Edit metadata permission
was checked, so a Viewer could edit every library they could see and an Editor could not be
limited to one library. Require Editor or Owner on the book's library for every metadata write,
including bulk edits, locks, covers, file renames, entity manager changes and author edits, and
hide the matching actions in the web client.
Keep existing access levels when an admin saves a user's library list. The old replace reset every
row to Viewer, which would now silently revoke editing on each user save.
Existing grants are Viewer, so after upgrading, admins must set Editor on each library where a
non-superuser should keep editing metadata. The released iOS app already gates editing on Editor.

Books often carry several files, such as an EPUB beside a PDF or an audiobook split into tracks.
Write-back reached only the primary file and the audio tracks, so the other formats kept stale
metadata.
Add an opt-in per-library mode that writes every content file of a book. Target selection,
capability reporting and the Files tab now share one role-aware selector, covers resolve per
medium, and results report per-format counts. Read-along EPUBs get their own toggle, off by
default, and their own size limit of 1000 MB, so they no longer follow the EPUB settings.
Live testing on copies of real libraries surfaced write-path bugs, fixed here as well:
- tag-only writes to chaptered M4B files failed because FFmpeg copied the chapter data track
- an undecodable cover failed every file instead of falling back to metadata only
- failure reasons stored the FFmpeg command line and absolute paths; they are now sanitized
- size limits used the stored size, so an unknown size bypassed them; writes now check the disk
- atomic replace dropped the file mode and ownership
- the EPUB temp name failed on long file names and could clash with a user file
- tracks in disc folders got duplicate titles
- a PDF worker that exited without a result hung its write forever; it now fails and times out
- null on a NOT NULL library setting returned 500 instead of 400
Generates migrations 0104 and 0105. Every new API field is optional, and released iOS builds
decode none of them.
Ref #694
Treat series positions as validated string labels so values such as 5.10 retain their exact representation across storage, metadata providers, file formats, and clients.
Closes#1119
Add server support for writing metadata, embedded covers, and FictionBook XML structures directly into FB2 format files. Introduce migration 0058 to persist FB2 file write preferences per library, and update library creator UI and locale catalogs.
