feat: Allow to show logs of all logging types by proxying messages

[susnux]

• Resolves #979

This creates an internal log file for all non file loggers, this enables showing all kind of logs. The internal log file is then rotated by a background job, I think rotation makes more sense to keep the behavior similar to the file logger log file. Maybe we can add a feature in the future to read also rotated logs (Nextcloud & internal log).

TODO

• [x] Log rotation / truncating is required otherwise the log would grow infinitely.
• [x] Adjust unit tests
