Plan 01 Summary: Paginator Enhancement + Shared Pagination Partial

What Was Built

Extended Pagination::Paginator with total_count and total_pages fields, then created a reusable pagination partial with page numbers, jump-to-page form, and prev/next navigation. Added a pagination_page_numbers helper for windowed page number arrays with ellipsis gaps.

Tasks Completed

1. Add total_count and total_pages to Paginator -- Extended Pagination::Result struct. Uses .count for AR relations, .size for arrays. Backward compatible.
2. Write unit tests for total_count and total_pages -- Tests for relation scope, array scope, empty scope, and backward compat.
3. Create pagination_page_numbers helper -- Added to ApplicationHelper. Returns array of page numbers and :gap symbols with configurable window.
4. Write tests for pagination helper -- Covers small ranges, large ranges (start/middle/end), and single page edge case.
5. Create shared pagination partial -- shared/_pagination.html.erb with page numbers, jump-to-page form, prev/next, Turbo Frame targeting, and extra_params preservation.
