Refactor cospend components and add SSR support to settle page

- Create reusable components: ImageUpload, FormSection, SplitMethodSelector, UsersList
- Replace duplicate code across add/edit pages with shared components
- Remove created-by info and edit/delete buttons from payments list
- Add server-side rendering support to settle page with form actions
- Fix settlement submission redirect issue
- Remove redundant back button from settle page
