core: remove uv cache clean | remove log rotation

[MickLesk]

✍️ Description

Removed the cache clean command for uv.
UV uses aggresive cache methods, so it can be only cleared with --force, thats in my opinion to unsafe for productive usage:

Example:
root@paperless-ngx:~# uv cache prune
Cache is currently in-use, waiting for other uv processes to finish (use --force to override)

Example with force:
root@paperless-ngx:~# uv cache clean --force
Clearing cache at: .cache/uv
Removed 118567 files (1.4GiB)

remove log rotation, because some apps need the journalctl to get login data or api key
