Fix PHP 8.5 curl_close() deprecation

[lohanidamodar]

Summary

• Remove the no-op curl_close($ch) call in Pay\Adapter that triggers a Deprecated notice on PHP 8.5.

Why

curl_close() has been a no-op since PHP 8.0 and is now formally deprecated in 8.5. The curl handle is freed when the variable goes out of scope.

Test plan

• composer lint (Pint) — pass
• composer check (PHPStan) — pre-existing failure on main unrelated to this change (pinned phpstan/phpstan: 1.9.x-dev is incompatible with PHP 8.4's stricter ReflectionClassConstant::IS_PUBLIC type signature). Repo CI does not run PHPStan.

Greptile Summary

Removes the curl_close($ch) call in Adapter::call() that has been a no-op since PHP 8.0 and is formally deprecated in PHP 8.5. The curl handle is already freed automatically when $ch goes out of scope at function return, so this change is correct and has no behavioral impact.

Confidence Score: 5/5

Safe to merge — single-line removal of a known no-op; no behavioral change.

The change is a well-understood, correct removal of a deprecated no-op API call with no side effects. No logic is altered.

No files require special attention.

Superseded by full migration to utopia-php/fetch (raw curl removed entirely, including this curl_close line). Closing in favor of the migration PR opening on a fresh branch.
