fix: update remaining imports in web-app actions to use shared-code

Fix imports in app/lib/actions/ that were still using relative paths
('../db-types') instead of the shared-code package.

Updated files:
- billActions.ts
- emailActions.ts
- locationActions.ts
- monthActions.ts
- navigationActions.ts
- printActions.ts
- userSettingsActions.ts

All imports now correctly reference @evidencija-rezija/shared-code.
