feat: add form validation for ekonomi module admin pages

- Added isFormValid() and isHtmlEmpty() helper functions
- Disabled submit buttons when required fields are empty
- Applied consistent validation pattern across all create/edit pages
- Validated fields: nama, deskripsi, tahun, jumlah, value, icon, statistik, and more
- Edit pages allow existing data, create pages require all fields
