refactor(kependudukan): improve TypeScript types and clean up code

- Add proper TypeScript interfaces for seeder files
- Rename MigrasiPendudukForm interface for consistency
- Separate asal/tujuan fields in MigrasiPenduduk API based on jenis
- Remove unnecessary eslint-disable comments
- Add local type definitions for public kependudukan pages
- Clean up unused imports (React, Flex, IconBuilding)
- Improve type safety in form handlers (handleChangeText vs handleChangeSelect)
- Add explicit type casting where needed to fix type errors
