fix(integrations): redesign integrations list table

[faisalahammad]

Summary

Replaces the Integration ID column in the LifterLMS settings Integrations table with a Description column (short blurb + Learn More link) and adds a new Configured column that indicates when an integration's required credentials are present.

Fixes #3150

Changes

includes/abstracts/llms.abstract.integration.php

Added three new public extension points so add-ons can declare their own configuration state and docs link without changing signatures.

public $learn_more_url = '';
public $configured_help = '';
public function is_configured() { return true; }

Why: add-ons need a way to tell the table whether keys have been provided, and where to send users for setup docs. Defaults preserve backward compatibility for any existing integration extending the abstract.

includes/integrations/class.llms.integration.bbpress.php and class.llms.integration.buddypress.php

Split the existing inline Learn More HTML out of $description into $learn_more_url, and added an is_configured() override returning true (no API keys required).

$this->description    = __( 'Restrict forums and topics to memberships and add forums to courses.', 'lifterlms' );
$this->learn_more_url = 'https://lifterlms.com/docs/lifterlms-and-bbpress/';

public function is_configured() { return true; }

Why: the previous $description was a single HTML blob with the docs link baked in. Splitting it lets the table render the blurb and the link independently and keeps the description clean for the per-integration settings page title.

includes/admin/settings/class.llms.settings.integrations.php

Replaced the Integration ID <th>/<td> with a Description cell and added a new Configured column between Installed and Enabled.

Before:

<th><?php esc_html_e( 'Integration ID', 'lifterlms' ); ?></th>
...
<td><?php echo esc_html( $integration->id ); ?></td>

After:

<th><?php esc_html_e( 'Description', 'lifterlms' ); ?></th>
...
<td>
    <?php echo wp_kses_post( $integration->description ); ?>
    <?php if ( ! empty( $integration->learn_more_url ) ) : ?>
        <a href="<?php echo esc_url( $integration->learn_more_url ); ?>" target="_blank" rel="noopener noreferrer"><?php esc_html_e( 'Learn More', 'lifterlms' ); ?></a>
    <?php endif; ?>
</td>

The Configured column follows the same tip--bottom-right / screen-reader-text / fa fa-check-circle pattern as Installed and Enabled. When is_configured() returns false, the cell shows a dash and uses $configured_help as the tooltip text (or Not configured if no help was set).

Testing

Test 1: bbPress row

1. Activate bbPress alongside LifterLMS.
2. Go to LifterLMS -> Settings -> Integrations.

Result: bbPress row shows the short blurb, a Learn More link opening https://lifterlms.com/docs/lifterlms-and-bbpress/ in a new tab, and checks in both Installed and Configured columns.

Test 2: BuddyPress row

1. Activate BuddyPress.
2. Reload the Integrations page.

Result: BuddyPress row shows its blurb, Learn More link, and both Installed and Configured checks.

Test 3: Inactive integration

1. With neither bbPress nor BuddyPress active, reload the page.

Result: rows render with the Integration ID column gone, Description populated, and the Installed/Configured columns showing dashes with tooltips.

Test 4: Coding standards

• vendor/bin/phpcs and vendor/bin/phpcs --error-severity=1 --warning-severity=6 both clean on the four modified files.
• php -l clean on all four.

@faisalahammad Thanks but for this feature request issue, "Installed" is basically already "Configured" for addons, so we don't need or want a new "is_configured" method that would need to be overridden. I'll close this for now as this issue will potentially need some coordination between the add-ons. We also have an internal task to decide the wording for each add-on.

As a general note we can't hard-code version numbers, it needs to be [version]
