style: unify logo position in all applications
Created by: HejdaJakub
- Position of logo is unified in all applications (by fixed left/right margin, auto top/bottom margin and limitation on max height). These changes are applied before log in and also after log in.
- On login page to user-profile is new label in nav bar.
- Property "logo_padding" was removed from admin-gui defaultConfig.json.
- Sign in button was also unified in all applications (black color and no border-radius).
