Bug: return false aborts entire sync loop on first API failure

[Valyrian-Code]

While reviewing sync-sched.php, I noticed that API failures inside the event sync loop currently terminate the entire sync process instead of skipping the failed event.

Current code (sync-sched.php, lines 53–55):

if ( is_wp_error( $data ) || ( wp_remote_retrieve_response_code( $data ) != 200 ) ) {
    return false;
}

This code runs inside a loop iterating through active events:

while ( $the_query->have_posts() )

Since the file is included from sync_sched(), return false exits the entire included file, not just the current iteration.

Impact

If a single sched.com API request fails (temporary 5xx, timeout, rate limit, etc.):

• processing stops for all remaining events
• later speaker/session data never gets synced
• sync failures happen silently
• update_option( 'lfevents_sync_sched_last_run', ... ) is skipped
• downstream speaker blocks may show stale or missing session data

This effectively turns one transient API failure into a full sync interruption.

Proposed fix

Skip only the failed event instead of aborting the entire sync process:

if ( is_wp_error( $data ) || ( wp_remote_retrieve_response_code( $data ) != 200 ) ) {
    continue;
}

This allows the loop to continue syncing the remaining events even if one API request fails.

Would like to work on this fix and open a PR for it, if that sounds good.
