Subject: [PATCH] feat(document): add Copy as Markdown action for documents

The CopyDocumentMarkdown view action already converts a collaborative content field to Markdown and copies it to the clipboard, but it was only registered for cards and controlled documents. Regular documents (document:class:Document) had no way to get their content as Markdown; copying selected text yields plain text with lots of extra blank lines.

Register the existing action for document:class:Document using its collaborative 'content' field, in the context menu ('copy' group) and the action palette.

Fixes #10301
