feat(reader): comic treatment for fixed-layout items in comics/manga libraries

PDFs shelved in comics or manga libraries (scanned manga, official manga
PDFs with text layers) now get comic reader treatment: bookmarks only —
no text-selection highlights, no annotations, no in-book search. Items
in ebooks libraries are completely unaffected, and EPUBs keep their
existing behavior everywhere.

- handlers: new exported ShouldTreatAsComic(libraryType, formatGroup) —
  true for fixed_layout/comic_archive in manga/comics libraries; the
  reader JSON API also exposes it as treat_as_comic
- router: the SSR reader page fetches the library type and passes
  TreatAsComic through ReaderMetadata into the init config
- reader: when treatAsComic is set, the PDF textLayer selection listener
  (mouse and touch paths) never attaches so no highlight popover can
  open; pointer mode is forced to pan (Smart/Text segment hidden);
  search button and toggleSearch are disabled; previously-created PDF
  highlights stop rendering
- bookmarks are unchanged (already page-index based for fixed layout),
  and device sync / OPDS / format classification are untouched since
  format_group stays fixed_layout
