Tell me, is there a regulatory document in Thailand that establishes that the stamp can only be extended to Russian citizens for 7 days, and not for 30, as for citizens of other countries?

An extension of 7 days is if you do not leave the country, but go to the immigration to add a week to your visa or stamp. This is not only for Russians, for many foreigners who have a stamp or a tourist visa.
