docs(cli-reference): add --no-filter flag to ocr review documentation

[lizhengfeng101]

Description

PR #835 (feat(cmd): add no-review cmd) added a --no-filter flag to ocr review that skips the REVIEW_FILTER_TASK post-processing phase. The code change has been merged, but the documentation site was not updated to reflect this new flag.

Currently missing from:

1. CLI reference pages — the ocr review flags table does not list --no-filter
2. i18n strings — the scanToggles key mentions --no-plan, --no-dedup, --no-summary but there is no equivalent entry for ocr review's --no-filter

For reference, the flag is defined in cmd/opencodereview/shared_flags.go and its help text reads:

// from shared_flags.go

The existing ocr scan stage toggles (--no-plan, --no-dedup, --no-summary) are documented — --no-filter for ocr review should follow the same pattern.

Scope

• File(s):
  • pages/src/content/docs/en/cli-reference.md
  • pages/src/content/docs/zh/cli-reference.md
  • pages/src/content/docs/ja/cli-reference.md
  • pages/src/content/docs/ru/cli-reference.md
  • pages/src/i18n/en.ts
  • pages/src/i18n/zh.ts
  • pages/src/i18n/ja.ts
  • pages/src/i18n/ru.ts
• Area: documentation site, CLI reference section

Acceptance Criteria

• --no-filter is listed in the ocr review flags table in all 4 locale CLI reference pages (en, zh, ja, ru)
• Description matches the actual flag behavior: skips the review-filter LLM call per file
• i18n files include an appropriate key for the review stage toggle (or the existing scanToggles pattern is extended)
• Docs site builds without errors (cd pages && npm run build)
