breadman: capture every stack page + the editor and new-note windows

--view (and now --screenshot) already opened any named stack page
directly, so the other 9 pages (upcoming/todo/reminder/idea/note/
question/archive/settings/errors) needed zero new code — just registry
entries in bread-capture.

Two more real windows needed actual wiring: the per-note editor popover
(editor::build_editor_popover, normally only reachable via a specific
note card's edit button — screenshot mode calls the builder directly
against the first real note in the store instead, since there's no
button handle to synthesize a click on) and the "New Note" modal
(show_add_note_window, same on_build-hook pattern already used for
breadbar's wifi add-network dialog).

The editor popover's first attempt parented it to the whole window,
which put it at GTK4 Popover's default Top position — entirely above the
window, clipped off the canvas in every capture despite mapping
successfully (no error, just invisible). Anchoring to a real button
(new_note_btn) with an explicit Bottom position fixed it.
