Intercept /support in the main bot with a dedicated handler (registered
like /start), replying with a fixed support-desk info message: the
operators' working hours and what to include (a description and, when
possible, screenshots). The reply is Russian or English by the sender's
reported Telegram language, and the command is listed in the bot's
command menu (localized).
Being a dedicated handler, it intercepts /support before the support
relay, so the command line itself is not forwarded into an operator
topic while the user's following description still is.
Update the telegram README and FUNCTIONAL.md (+ _ru mirror).
