perf: avoid full refresh after new note

[Clearner1]

Summary

• Save the deferred Mac Durable Outbox design in docs/mac-outbox-proposal.md.
• Keep the proposal explicitly unimplemented and preserve Anki as the current source of truth.
• Remove only NewNoteDialog's onCreated={refreshAfterWrite} wiring so a successful new-note flow no longer waits for the full note/navigation refresh.

Preserved behavior

• AnkiConnect addNote flow remains unchanged.
• Short Note suspend and areSuspended verification remain unchanged.
• Toasts and dialog close behavior remain unchanged.
• EditModal still calls refreshAfterWrite through onUpdated.
• No dependency, cache, abstraction, route, or style changes.

Checks

• git diff --check passed.
• Local tests were not run because this managed worktree has no node_modules; dependencies were not installed.
• PR CI should run the repository's full npm run check.
