Replace OnTheFly.js with OnTheFly.ts and introduce ThirdPartyEdit.vue for enhanced third-party entity management

- Migrated API functions in `OnTheFly.js` to `OnTheFly.ts` for improved type safety using TypeScript.
- Added `ThirdPartyEdit.vue` to streamline third-party creation and editing with a Vue component structure.
- Updated third-party-related types in `types.ts` to improve consistency and explicitly distinguish `company`, `contact`, and `child` entities.
- Enhanced `AddPersons.vue` and dependent components to support adding third-party contacts.
- Adjusted styles and removed `.btn-tpchild` for consistency in button definitions across SCSS.
