♻️ refactor(admin): update area selection component API and logic

- change API query parameters from individual fields to filters JSON object
- modify default option value from empty string to 'none' for better type safety
- update ID parsing logic to check for 'none' value explicitly
- standardize empty selection handling across province, city and district components
