feat: add full Russian (ru-RU) localization — v0.50.95 (PR #713)

Full Russian locale — 389/389 English keys, Slavic plural forms, native Cyrillic. Rebased from PR #605 with rebase artifacts fixed. Login page Russian added to api/routes.py. Credits: @DrMaks22 (translation), @renheqiang (PR #605 author).
