fix: adapt tests for last-page-only dismiss and fix editor z-index

- SystemNoticeModal tests: navigate to last page before testing
  X button, ESC, and CTA dismiss (matches new last-page-only behavior)
- EntryEditor: use z-[9999] instead of portal (fixes iOS stacking
  without breaking test DOM queries)
- Pros/cons inputs: remove colored backgrounds in dark mode
