Remove the settings/backups

[j-zimnowoda]

Is your feature request related to a problem? Please describe.

There are two places where backups are defined.

1. menu -> backups
2. menu -> settings -> backups

The first one is generic setting for PV backup The second one is platform specific backups and database backups

Platform PV backup may not make sense for many core application since there is already functionality to perform database backups.

Describe the solution you'd like A clear and concise description of what you want to happen. We would like to

• [ ] remove 1) menu -> backups
• [ ] add platform PV backup to 2) - only for gitea
• [ ] add 3) menu -> settings -> databases, where user can define DB parameters fro core apps and toggle DB backup functionality.
