In app search improvements feature branch (#51413)

* Add search results count to the in-app marketplace (#51266)

* Add searchResults to context

* Use setSearchResults in Content

* Add ribbons to the tabs

* Changelog

* Use setState as the function name

* Only show ribbon counts when there's an active search

* Refactor how 'setSearchResultsCount' is used (h/t @mcliwanow)

* Don't populate initial search results

* Unify css styling

* Marketplace: bring back the loading state (#51342)

* Marketplace: bring back the loading state

* Add changefile(s) from automation for the following project(s): woocommerce

---------

Co-authored-by: github-actions <github-actions@github.com>

* Remove in-app marketplace Search results tab and unify results into existing tabs (#51297)

* Remove search results component and any references to it

* Persist current tab for searching, or default to extensions if tab is not set

* Persist term when switching across tabs

* Lint

* When a search is initiated, fetch all categories to keep the tab counts up to date.

The necessary filtering to display data to the current screen will be performed on the frontend.

* Apply correct colors to the tabs, as per design

* Beyond query.term, also rely on isLoading so that search result counts don't jump

* Address an issue when the user searches for something that returns no results in the business services tab

* Changelog

* Addressed :)

* Change key to category

* Fix category filter being broken

Whenever a category is requested, we need to do an additional request with the category param being the current category (overriding extensions/theme/business services).

Ideally the backend API would make a distinction between type (theme/extension/business service) and category, but this hack should do for now.

* Lint

* Remove unused variables h/t @KokkieH

* Lint

* Revert "Lint"

This reverts commit 0b2d2dca6d.

* Actually fix lint without introducing infinite loop

Reproducible at http://localhost:8080/wp-admin/admin.php?page=wc-admin&term=payments&tab=extensions&path=%2Fextensions&category=customer-service

* Show category selector even if there are no results displayed

* Update comment to be less misleading

* Query isn't used here

* Update Marketplace search component (#51313)

* Update Search placeholder text

* Replace search component with one from @wordpress/components

* Make mobile search field font consistent with desktop

* Add changefile(s) from automation for the following project(s): woocommerce

* Handle import errors for SearchControl component

* Marketplace: update category selector (#51309)

* Marketplace: update category selector

Remove the dropdown on the desktop view and show all items, even if
overflowing. Added helper buttons to scroll to the right to show more.

* Add changefile(s) from automation for the following project(s): woocommerce

* Marketplace: remove category sroll helpers from tabindex

GitHub:
https://github.com/woocommerce/woocommerce/pull/51309/files#r1758448638

* Marketplace: Remove selectedTab reference from product.tsx

This is probably included due to the merge conflict

* Marketplace: tweak category scroll button narrower

---------

Co-authored-by: github-actions <github-actions@github.com>

* Lint

* Fix 2 lint errors

* Fix another lint error (useMemo) h/t @KokkieH

* Add load more button in-app (#51434)

* Add additional fields returned by search API to marketplace types

Ensure components have access to additional fields

* Add LoadMoreButton component

* Only render Load More button if there are additional pages of results

* Fetch and display next page of results in Load More button is clicked

* Simplify renderContent function to have less repetition

- Hide load more button while fetching results

* Improve loading of new products

- Ensure keyboard focus goes to first new product after Load More is clicked

* Add changefile(s) from automation for the following project(s): woocommerce

* Add blank line to separate sections

* Set category param based on current tab when loading more products

* Improve busy-state screen reader text

Co-authored-by: Boro Sitnikovski <buritomath@gmail.com>

* Add missing dependency

* Move getProductType() function to functions.tsx

- Do not show load more button if isLoading state is true

---------

Co-authored-by: Boro Sitnikovski <buritomath@gmail.com>

* Rework the values used with `setSearchResultsCount`

After https://github.com/Automattic/woocommerce.com/pull/21678/files we
get a `totalProducts` so we can re-use that.

Also remove setting the counts when paginating since we set them to the
total.

* Add search complete announcement h/t @KokkieH

* Show update count only if greater than 0 h/t @andfinally

* Switch to Extensions tab if on My subscriptions when searching

* yoda
