fix: align SSO test defaults

[superdav42]

Summary

• Align SSO coverage setup with the enabled SSO path and restore the domain-mapping redirect-host callback removed by test cleanup.
• Persist and clean up the enabled SSO setting in the setting test.

Testing

• Passed: php -l tests/WP_Ultimo/SSO/SSO_Coverage_Test.php
• Passed: php -l tests/WP_Ultimo/SSO/SSO_Extended_Test.php
• Blocked locally: Composer 2.10.2 could not download three locked packages because GitHub authentication is unavailable and Composer reported no git binary for source fallback. Consequently vendor/bin/phpunit and vendor/bin/phpcs are unavailable; CI must run the focused and full PHP matrix.

Resolves #1747

Summary by CodeRabbit

• Tests
  • Improved single sign-on test coverage for domain-mapped redirects.
  • Updated setting tests to verify saved SSO configuration values and restore test state afterward.
  • Ensured redirect behavior is tested using the standard SSO initialization flow.

📝 Walkthrough

Walkthrough

The pull request updates two SSO tests to match disabled-by-default SSO behavior. The tests now initialize the redirect-host callback through SSO::init() and explicitly persist and restore the enable_sso setting.

Changes

SSO test repairs

Layer / File(s)	Summary
Redirect-host test setup tests/WP_Ultimo/SSO/SSO_Coverage_Test.php	setUp() restores the domain-mapping redirect-host callback. The test initializes SSO through init().
SSO setting test state tests/WP_Ultimo/SSO/SSO_Extended_Test.php	The test saves enable_sso as true, verifies the stored value, and resets it to false in finally.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 03e79

The PR changes SSO test setup and cleanup, but one test can leave the shared SSO setting changed when it was previously enabled, causing order-dependent test failures. The PR is mergeable with explicit owner awareness and follow-up to restore the original setting.

Merge summary

• Restored the domain-mapping redirect-host callback in SSO coverage setup after test cleanup removes temporary callbacks.
• Exercised redirect-host setup through the enabled SSO initialization path.
• Made the enabled-setting assertion persist and clean up its explicit setting.

Verification

• Passed: PHP syntax checks for both changed tests.
• Local PHPUnit and PHPCS are unavailable because Composer dependency installation could not authenticate three GitHub package downloads and no source-fallback Git binary was available to Composer.
• Remote CI must validate the PHP matrix.

to capture the previously persisted enable_sso value before setting it to true,
then restore that captured value in the finally block instead of always saving
false; keep the existing assertion unchanged.
