dotCooCoo 9e90464f20 PDF/.ai import: dictionary values the reader can't parse no longer crash the ink and font scans
The reader's Dict::entries unwraps every value it reads, so it panics on
a value it cannot parse, such as the name /#zz or the number 12-.5
(vendor/hayro-syntax/src/object/dict.rs:104 at craft-libs ca50d63b).
Besides the nesting check in pages.rs, two loops of the import call it:

- Colors::visit (import_color.rs) looks for the file's Separation and
  DeviceN spaces when a page paints in one. craft_pdf's interpret_page
  catches the panic, and the import fails with "PDF page interpretation
  failed internally".
- Walker::note_fonts (import_scan.rs) notes the fonts of each page. The
  import does not catch that panic.

On main the nesting check in pages.rs panics on such a value first
(#2133 fixes it); with it fixed, the import reaches these two loops.

Colors::visit now reads the values with Dict::keys and get_raw, sorted
by key as before, and leaves out a value the reader cannot parse.
note_fonts reads the keys and looks each font up by its key, as before.
