add bulk actions to log page

[matiasqueroceballos]

Description:

Summary

• Convert bulk resend from synchronous HTTP requests to asynchronous Action Scheduler jobs
• Eliminates 30+ second blocking delay; AJAX now returns instantly
• Each log resend is staggered by 1 second to prevent simultaneous CRM API calls
• Frontend displays simulated progress for 4 seconds while backend processes in background
• User is no longer blocked on error log page during bulk operations

Changes

• class-error-log.php: ajax_bulk_resend_logs() now enqueues jobs instead of processing sequentially
• error-log.js: Updated to handle instant response and show 4-second completion message before reload
• Removes 20 sequential CRM API calls from request handler; offloads to background queue

Benefits

• Dramatically faster user experience (instant feedback vs 34 seconds)
• Better resource utilization (background processing)
• Prevents timeout errors on large bulk operations
• Uses existing retry_failed_entry() hook infrastructure

Testing

• Select 20 logs and trigger bulk resend
• AJAX completes in <100ms
• Progress bar displays for 4 seconds
• Page reloads with updated entries
• Verify Action Scheduler shows queued jobs in admin UI

@davidperezgar esto es un añadido interesante, de parte de Alicia. Quieren poder borrar sólo algunos registros del log así que se han añadido buls action para poder hacerlo fácilmente por ellos desde la tabla de log
