RTR#22 Further improvements interspersed with code refactoring

Today, I fixed some visual shortcomings. It is now possible to change images during post editing. The rules of the magazine have been included in the description on Fediverse to avoid misunderstandings with Lemmy users. Some changes are already on the instance, and the rest will be pushed by morning.

At the beginning of next week, I will also unlock Mercure, so you will be able to enable the dynamic feed.

Currently, I need to handle communication on Fediverse, and then I'll return to code refactoring.
