fix(video-editor): address CodeRabbit review of region clipboard

- Fix handleCopySelected loop so stale ids fall through to the
  'nothing to copy' toast instead of silently returning.
- Use regionClipboard.kinds.blur label when copying a blur region.
- Add 'blur' to regionClipboard.kinds in all 13 locales; broaden
  the 'annotation' label to neutral terms in es/fr/it/ja-JP/ko-KR/
  pt-BR/ru/tr/zh-CN so the toast no longer reads 'Text' for blurs.
- Cover the placement-at-region-start boundary in regionPlacement
  tests.
