Field notebook: capture NPC lines, tear pages onto the board

A dialogue line gains a "✎ Note this" capture that saves it to a
per-playthrough notebook (migration 035 + notebook endpoints). The inventory
notebook lists captured pages in a handwriting font (Google "Reenie Beanie")
and "✂ Tear to board" drops a page onto the current board as a note exhibit
(reusing addNote), then removes the page. Board notes render handwritten too.
