- handle document paste: images become the entry photo when none is set,
otherwise they land in "Файлы проекта" along with any other pasted files
- take file names from the clipboard, replace generic ones (image.png, blob)
with "Вставка <date>.<ext>"; derive extension from MIME when missing
- validate client-side like the server: 10 files, 10 MB per file, 30 MB total,
reject blocked extensions (*.html, *.js, *.svg, ...)
- share the limit logic between the picker and paste, send the photo under its
real name so pasted PNG/JPEG keep their extension
- add Ctrl+V hints to the photo and files cards (hidden on touch devices)
