refactor: standardize pagination across all admin pages

Migrated marketplace.js, imports.js, and logs.js to use the same
pagination pattern as companies.js, users.js, and vendors.js:

- pagination: { page, per_page, total, pages }
- Computed getters: totalPages, startIndex, endIndex, pageNumbers
- Methods: previousPage(), nextPage(), goToPage()

Updated templates to use the shared pagination macro:
- marketplace.html
- imports.html
- logs.html

All admin pages now use consistent pagination behavior and styling.
