fix: context menus offer only what applies to what was clicked, disabled when it can't
Clover: New Notebook isn't about the notebook right-clicked, so its menu drops
it. Sections gain OneNote 2010's Copy Link to Section, as the lab's OneNote
copies it. New Section, New Section Group and Customize Font Styles are
disabled where the notebook has no catalog or the section no identity, and the
page's Cut, Paste, Link, Remove Link and equation forms where the page takes
no edits.
