feat(falukant): enhance marriage actions with production delay handling and UI updates

- Implemented logic in FalukantService to delay running productions when spending time with a spouse, updating the start timestamp accordingly.
- Enhanced the response from the spend time API to include details about delayed productions and household order changes.
- Updated FamilyView component to display the cost of marriage actions and added a help section detailing the effects of actions, including production delays.
- Added new translations for action effects in multiple languages to improve user understanding of the marriage actions.
