fix(review): clean up dynamic review copy

[limityan]

Summary

• remove retired fixed-reviewer presentation resources and keep the UI aligned with dynamic, evidence-driven review checks
• replace internal or misleading copy with plain, count-neutral wording across English, Simplified Chinese, and Traditional Chinese
• localize managed review batch cards without changing persisted packet identities or historical report compatibility
• add locale, fallback, task-card, consent, and report-label regression coverage

This is a focused follow-up to #1723. Historical reviewer IDs and report coverage categories remain supported; only current user-facing presentation is cleaned up.

Validation

• 110 focused Web UI tests passed
• Rust review-team contract tests passed (3/3)
• pnpm run type-check:web
• pnpm run lint:web
• pnpm run i18n:contract:test
• pnpm run i18n:audit (0 warnings)
• pnpm run theme:color-audit:all
• cargo check -p bitfun-agent-runtime
• pnpm run check:repo-hygiene
• git diff --check

Full Web UI run completed with 1972/1973 tests passing locally; the sole failure is an unchanged RemoteConnectDialog source-text contract that assumes LF line endings and fails on this Windows CRLF worktree.
