fix(tgbot): resolve client creation race conditions and localization bugs

- Refactored Telegram bot client creation state to use a concurrent-safe map (\clientStates map[int64]*ClientState\), replacing package-level global variables. This prevents data races when multiple administrators interact with the bot simultaneously.
- Fixed hardcoded English strings in \BuildInboundClientDataMessage\ by utilizing the \	.I18nBot()\ localization wrapper.
- Implemented \UpdateBotLocalizer\ to dynamically refresh the bot's language whenever the \	gLang\ setting is updated in the web panel, eliminating the need for a service restart.
- Synchronized missing translation keys for \Sub ID\ and \Flow\ across all non-English/Russian localization files to prevent missing interface elements.
