Improve plan review UX with enriched rows, TUI filters, and execute gate.

Make review-plan easier to act on: Chinese risk labels, relative paths,
verdict/next-step footer, optional identity/analysis enrichment, grouping,
spot-check sampling, and structure preview. Extend the TUI with filters,
duplicate-group reject, and quality context. Persist review_context on
plan operations and add --require-review for confirmed execute.
