Fix/resend errors

[matiasqueroceballos]

Description

Implements cascading automatic retry logic for failed CRM form submissions using WordPress Action Scheduler. When a submission fails, the system automatically schedules up to 3 retry attempts, each scheduled 1 hour apart.

Changes

• Modified retry_failed_entry() to properly handle cascading retries
• Fixed response status check to match actual CRM API responses (status: 'ok')
• Pass log ID to create_entry() for proper tracking
• Register formscrm_retry_failed_entry hook globally (outside admin context) so Action Scheduler can execute it
• Removed attempt limit from manual resend button (unlimited manual retries allowed)
• Manual resend button no longer increments automatic retry counter
• Fixed UI NaN issue by reloading page after successful manual resend

How It Works

1. Form submission fails → log created, first retry scheduled for 1 hour
2. First retry executes and fails → second retry automatically scheduled
3. Second retry executes and fails → third retry automatically scheduled
4. Third retry executes and fails → no more automatic retries
5. Manual resend button available unlimited times regardless of automatic attempt count

Testing

• Verified cascading retries create Action Scheduler actions in sequence
• Confirmed each retry increments attempt counter (1/3, 2/3, 3/3)
• Tested manual resend button works after max automatic attempts reached
• Verified debug logging captures all retry lifecycle events
