Important notices and draft reliability

Add interactive notifications in the upper-right corner for restored drafts, auto-save failures, settings-save failures, and history recovery, with dismiss, history, and retry actions.
Show “Your last draft has been restored” only when startup actually restores a non-empty draft, clearly distinguishing saved edits from an image that has not been exported.
Fix Smiley Sans drafts failing validation during shutdown, which could prevent the app from closing after it could not save the draft.
Align font-scheme card headings, descriptions, and row heights while keeping each preset font limited to its font-name sample.
