fix(i18n): the Russian pack says вы to the user throughout

[kurktchiev]

ru.js speaks to the user in two registers. The Coach, the sync messages and the gym card say вы ("Ваш план готов", "Добавьте карту зала"). Sign-in, the plan, the workout screen and the progression hints say ты ("Введи пароль", "Твой недельный план", "Продолжай: нажми «+ Добавить упражнение» ниже"). Two lines in sheets.jsx that say the same thing disagree: 'Finish your current workout first' is «Сначала завершите текущую тренировку», and 'Finish the current workout first.' is «Сначала заверши текущую тренировку.»

I counted strings, not lines, by every second-person form: ты and вы in all cases, твой and ваш, imperatives, 2nd-person verbs, and past forms that stand for "you did" («Забыл?», «Побил цель в нём, и вес растёт»). The word lists come from the pack's own vocabulary, sorted by hand. 180 strings address the user with ты, and every other string that addresses the user says вы. No string mixes the two.

This PR moves the 180 to вы. Two of them are the pairing messages ('Open Settings → Account → “Pair the mobile app”…'), which said вы until 0960110 (the Settings rework) rewrote them with ты. Only the register changes: нажми → нажмите, твой → ваш, у тебя → у вас, будешь → будете, Забыл? → Забыли?, Ты это отклонил → Вы это отклонили. With the Cyrillic letters masked, each old and new string match character for character, so word order, punctuation and placeholders are untouched. One string is reworded. In 'Turning this off removes you from the numbers immediately', «Выключишь, и сразу исчезнешь из цифр» would have become «Выключите, и сразу…», which reads as an instruction, so it says «Если выключите, сразу исчезнете из цифр». After the change no string says ты to the user.

Five strings are the user talking to the Coach, and the first commit leaves them alone: the lines the chat posts for the user when a quick action is tapped ('Have a look at my training and tell me what you would change.', 'Build me a fresh plan from my answers.', 'Improve my routine “{0}”.'), the instruction sent with the last one ('Focus only on my routine “{0}”. …'), and an example line no screen uses ('e.g. “swap the squats for split squats, and Mondays are short”', which #415 removes). Four say ты to the Coach and 'Have a look at my training…' said вы.

The second commit brings three smaller things in line with the rest of the pack:

• 'Have a look at my training and tell me what you would change.' says ты to the Coach, like the other four: «Посмотри на мои тренировки и скажи, что бы ты изменил.»
• The Coach was «Коуч» in five strings and «Тренер» in 74. The five say «Тренер» now, in the case each one needs: у Тренера, Тренер работает, предлагал Тренер, План Тренера, истории Тренера.
• Two import messages said «{0} рутин» where 74 strings say «программ…» for a routine. They say «{0} программ», the same genitive plural.

No string uses вы for several people at once, so nothing needed an exception.

Both commits were made by Claude, and no native Russian speaker has checked them.

Tests: no test reads these Russian strings. With both commits, check-locales.mjs: 17 locales, 1,979 keys each. check-source-strings.mjs --strict: 1,555 strings, all in the packs. pt-br-locale.test.js passes with the fingerprint unchanged. The full frontend suite passes on 39bc71e.

No open PR gains a conflict from this branch.

Five open PRs add strings that say ты: #391 (30), #82 (8), #312 (7), and #177 and #373 one each. Whichever of them lands after this one brings the mix back unless those strings move to вы as well. No open PR adds a string with «Коуч» or «рутин». This branch also merges cleanly with #415.
