Collapse the two per-language Telegram bots into one unified bot and
replace language-based variant gating with explicit per-user variant
preferences.
- Telegram: one bot; drop service_language and the supported_languages
set everywhere (DB, account, auth, FlatBuffers Session wire, gateway,
connector proto). The single bot renders chat and out-of-app push in
the recipient's preferred_language; remove the game-language push
routing override (notify Intent.Language / push Event.language).
- Preferences: new accounts.variant_preferences (text[], DB default
{erudit_ru}, CHECK non-empty + subset of the three variants). Gates
the New Game picker, vs-AI and the friend invitation the player
creates, enforced server-side (HTTP 400 otherwise); an invited friend
may still accept any variant. Edited on the Settings screen; variants
are Erudit-first everywhere.
- Admin: drop the per-bot language selectors (broadcast / send-to-user)
and the feedback channel_lang column/field.
- Env/CI: collapse TELEGRAM_BOT_TOKEN_{EN,RU}, TELEGRAM_GAME_CHANNEL_ID_{EN,RU},
VITE_TELEGRAM_LINK{,_EN,_RU} and VITE_TELEGRAM_GAME_CHANNEL_NAME_{EN,RU}
to single unsuffixed names; drop GATEWAY_DEFAULT_SUPPORTED_LANGUAGES.
- Docs updated (ARCHITECTURE, FUNCTIONAL + _ru, platform/telegram, gateway,
backend, ui, UI_DESIGN, PRERELEASE).
The migration squash is deferred to a follow-up PR.
