The "Print" button on a printer card (and drag-drop-onto-card) used
FileUploadModal to persist the file as a LibraryFile, then dispatched
through POST /library/files/{id}/print. The LibraryFile row + disk file
were left behind after every one-off print, polluting File Manager with
entries the user never asked to save.
FilePrintRequest.cleanup_library_after_dispatch (default False) opts
into post-dispatch cleanup. When set, _run_print_library_file stages
db.delete(lib_file) in the same transaction as archive_print so a
mid-flight FTP / start_print failure rolls both back cleanly, commits
together, then unlinks the library disk file + thumbnail after commit
succeeds. External library files (is_external=True) are never touched.
Only the Printers-page Direct-Print PrintModal sets the flag. Every
other api.printLibraryFile caller (File Manager Print, Project Detail
Print) leaves it unset — their entries are there by user intent.
Also moves formatPrintName out of PrintersPage.tsx into a new
utils/printName.ts module — fa1c46d9 (#881) exported it inline so its
test could import it, tripping react-refresh/only-export-components.
