Lower duplicate-job logs to info; keep unexpected failures as errors

[KunBojiMan]

Summary

Duplicate job scheduling/running is expected in some flows. These were logged as errors and triggered noisy alerts without indicating a real issue. This PR lowers those to info while keeping unexpected failures at error level.

Changes

• Catch JobAlreadyRunningException and JobAlreadyScheduledException and log at info.
• Keep other throwables at error to preserve visibility.

Implementation note

use Klaviyo\Integration\Exception\JobAlreadyRunningException;
use Klaviyo\Integration\Exception\JobAlreadyScheduledException;

} catch (JobAlreadyRunningException|JobAlreadyScheduledException $e) {
    $this->logger->info($e->getMessage());
} catch (\Throwable $e) {
    $this->logger->error($e->getMessage());
}

Testing

Low. Behavior unchanged except for log level; genuine failures still surface as errors.

Manual run of the affected scheduled tasks to confirm expected info-level log entries and unchanged error handling.
