Improve `logs` module to log username changes and channel creation/deletion

[Elanis]

In the process to stop using Dyno on "Not a name" server, we will need these features to be added in Not A Bot.

The current logs module is used to log deleted messages from channels. We also need to log username changes and channel (and if possible Threads) creation/deletion to make moderation task easier.
