Subject: [PATCH 3/4] MERL-1228: Fix issue with rewriting links to front end
 (#1624)

* test: confirm content replacement behavior with a mixed content blob

* test: confirm unrelated URLs are untouched

* chore: add `use_wp_domain_for_post_and_category_urls()` function.

Determines if post and category URLs should link to the WP site.

* chore: add `use_wp_domain_for_media()` function.

Determines if WP media URLs should link to the WP site.

* chore: remove callback attached to `graphql_request_results` filter

* chore: use new `use_wp_domain_for_post_and_category_urls()` function inside `domain_replacement_enabled()`

* fix: adjust content replacement logic to avoid rewriting media links incorrectly

* filter block content via `wpgraphql_content_blocks_resolver_content`

* refactor: Adjust logic in `image_source_srcset_replacement`

* chore: add changeset

Subject: [PATCH 4/4] MERL-1270: Do not rewrite links in the post editor
 (#1625)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: do not rewrite links in the post editor

When Faust’s “Enable Post and Category URL rewrites” is enabled, this has been causing URLs to be rewritten in the editor to contain the front-end URL instead of the WP URL, which causes them to be saved to the database this way. Instead, we want the WP URL saved to the database.

* fix: don't rewrite links in `wp-link-ajax` ajax requests

* fix: do not rewrite links on permalink generation requests

* test: confirm post_link filtering behavior.

Confirms links are not rewritten on post-new.php pages when $_POST is empty. Also confirms Ajax requests to generate sample permalinks are not rewritten. These checks prevent the incorrect guid from being written to the database.

Confirms `wp-link-ajax` Ajax requests are not rewritten. This is used by the Classic Editor when linking content.

chore: update `enable_rewrites` values in tests to be `1` instead of `true`, for consistency.

* add changeset

* refactor: extract conditional logic to functions

+Fixed a bug where links were rewritten to the Faust Front-end Site URL when using the post editor, resulting in those rewritten links being saved to the post content and guid fields when they shouldn't be. These links are now saved with the URL pointing to the WP site, as they should be. They are still rewritten at runtime to link to the Front-end Site URL when appropriate.
