feat(falukant): refactor character ID resolution for political office checks

- Introduced a new method `resolveCharacterIdForOfficeChecks` to robustly resolve character IDs based on user references, improving the reliability of political office queries.
- Updated `getHighestPoliticalOfficeInfo` and `getHighestOfficeAnyInfo` methods to utilize the new character ID resolution logic, enhancing code clarity and reducing redundancy.
- Ensured that character ID retrieval handles both direct and fallback user references, streamlining the process of fetching political office information.
