fix(i18n): update ru-RU i18n (unify terms, phrases)

[axsapronov]

Summary

I saw a lot of strange russian words in UI. In this PR I tried to unify terms, phrases after auto-i18n.

Validation

$ tsx ./scripts/check-i18n.js --lang ru-RU
🚀 Starting i18n:check script...
🌍 Checking languages: ru-RU
{ 'ru-RU': 0 }
Missing keys in ru-RU: []

✅ All i18n files are in sync

Pull request overview

This PR updates the web Russian locale (ru-RU) to improve UI wording consistency and replace awkward/incorrect machine translations across multiple product areas (Workflow editor, tools/integrations, datasets/knowledge, billing, auth, etc.).

Changes:

• Refines Russian phrasing and terminology across Workflow/Knowledge/Dataset UI strings.
• Translates previously-untranslated English strings and normalizes labels/placeholders.
• Updates a large set of i18n JSON resources to keep ru-RU in sync with other locales.
