feat: Add Page X of Y indicator to pagination controls

[TarunyaProgrammer]

Add page indicator to catalog pagination (Page X of Y)

What this PR does

This PR adds a page indicator to the catalog pagination UI to display the current page and total number of pages (e.g., Page 2 of 6).

The enhancement improves navigation clarity while keeping pagination entirely client-side.

---

Problem

The catalog pagination on https://meshery.io/catalog/designs currently only provides “Prev” and “Next” buttons.

As a result, users cannot:

• identify the current page
• know how many pages exist
• estimate how much content remains

This makes navigation less intuitive, especially when browsing large result sets.

---

Solution

• Introduced a small page indicator (Page X of Y) in the pagination UI.
• The indicator updates dynamically when:
  • navigating between pages
  • applying filters or search queries
• No backend changes are required.

---

Implementation details

• Pagination is fully client-side and already calculates total pages using:
  • matchingCards.length
  • itemsPerPage
• Logic is centralized in _includes/patterns-filter.html.
• This PR:
  • adds a lightweight UI element for page info
  • updates the existing pagination logic to inject the page text

This ensures accuracy even when the result set changes due to filtering.

Summary of Changes

Hello @TarunyaProgrammer, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the user experience of the catalog pagination by introducing a "Page X of Y" indicator. This client-side enhancement provides users with immediate context about their current position within large result sets and the total number of available pages, addressing a previous limitation where only "Prev" and "Next" buttons were present. The changes are purely frontend, integrating seamlessly with existing pagination logic.

Highlights

• Pagination Clarity: Implemented a "Page X of Y" indicator for catalog pagination, enhancing user navigation by providing context on the current page and total pages.
• Client-Side Solution: The entire feature is implemented client-side, leveraging existing JavaScript logic without requiring any backend modifications.
• Dynamic Updates: The page indicator dynamically updates in response to page navigation, filtering, and search queries, ensuring accuracy with changing result sets.
• Centralized Logic: Core logic for the indicator is integrated into _includes/patterns-filter.html, ensuring consistency across different catalog views.

Changelog

• _includes/patterns-filter.html
  • Added CSS styling for the new .page-info element to control its appearance.
  • Implemented JavaScript logic within the updatePaginationButtons function to calculate and dynamically display the current page and total pages within the .page-info element.
• collections/_pages/designs.html
  • Injected a <div class="page-info"></div> element into the pagination structure to serve as the placeholder for the page indicator.
• collections/_pages/filters.html
  • Injected a <div class="page-info"></div> element into the pagination structure.

Code Review

This pull request successfully adds a page indicator to the catalog pagination, which is a great usability improvement. The implementation is straightforward and correctly handles the client-side logic. I have one suggestion to make the JavaScript selector more robust and maintainable.

This PR adds a small frontend-only page indicator (Page X of Y) to catalog pagination.
All logic is client-side and centralized in _includes/patterns-filter.html.
