feat: add unification handler and inheritance system

- Implemented `unificationHandler.ts` to manage nation unification logic, including inheritance point calculations and logging.
- Created `InheritView.vue` for frontend management of inheritance points, buffs, and logs.
- Added database migration for new inheritance tables: `inheritance_point`, `inheritance_log`, `inheritance_result`, and `inheritance_user_state`.
- Developed inheritance buff logic in `inheritBuff.ts` to apply buffs during domestic and war actions.
