Describe the bug
When using WP Rocket with SpinupWP, we disable our cache, and only sync full site cache purging:

wp-rocket/inc/ThirdParty/Hostings/SpinUpWP.php

Line 29 in b11a9ef

'after_rocket_clean_domain' => 'purge_site',

Individual pages cache purge is not synced.

They do have a way to purge individual URLs are well:

function spinupwp_purge_url( $url ) {
    return spinupwp()->cache->purge_url( $url );
}

https://github.com/spinupwp/spinupwp-plugin/blob/62ae3ec7c53f602f80cd10c742fae6c361c790f4/functions.php#L38-L40C6

We should hook to this method whenever after_rocket_clean_post is triggered.

To Reproduce
Steps to reproduce the behavior:

1. Use SpinupWP
2. Purge an individual page
3. See that the page is not purged from the server-side cache (it will still have Fastcgi-Cache: HIT response header returned)

Expected behavior
We should also sync individual pages cache when needed to ensure page content is always current.

In this PR we need to make sure that specific URL of their cache are cleared when:

1. Clicking on the Purge URL from the admin top bar
2. When Used CSS for specific URL is generated
3. The whole cache should not be cleared in the above scenarios

Scope a solution ✅

In the SpinUpWP compatibility class, we can add methods to purge individual URLs, using the provided function by the host, with a check with function_exists() before using it.

We should use it for the following hooks:

• after_rocket_clean_file
• rocket_rucss_after_clearing_usedcss
• rocket_rucss_complete_job_status
• after_rocket_clean_term
• rocket_after_clean_terms

Estimate the effort ✅

Just want to clarify that SpinupWP doesn't host any servers. Thank you.

you will need to bring your own server for SpinupWP to connect to
