Replace manual confirmations with [confirm] attribute in destructive commands

- Add [confirm] attribute to all destructive operations:
  - volumes-clean-all, volumes-remove, volumes-remove-pattern
  - postgres-drop-database, postgres-restore
  - mysql-drop-database, mysql-restore
- Remove manual read -p confirmations and conditional logic
- Simplifies code and uses Just's built-in confirmation system
- Ensures consistent confirmation behavior across all destructive operations

This provides better UX and cleaner code using Just's native features.
