M7: editor keyboard + one-click card toolbars (live-pass fixes)

From the unified-editor live pass (task 1922):

- Esc now returns to the base Notes board from any view (AppShell); an open editor consumes Esc first (its handler stops propagation) so it closes before navigating.

- Ctrl/Cmd+Enter = finish & close in BOTH frames — it already closed the modal editor; now it also commits+collapses the board composer (matches the email/chat 'send' convention). Shift+Enter still saves & starts a new note.

- Fix: the inline composer committed on document mousedown, collapsing and shifting the board before a click landed — so clicking another card's pin/archive/trash took two clicks. Commit on click (bubble phase) instead; the target's action fires first, then the composer closes.

Pure frontend.
