[XB] Batch Update Custom Fields 1.0.0

Batch update thread custom fields using XenForo's standard thread batch update tool.

This add-on extends the batch update interface with native custom field controls, allowing administrators to update selected field values across multiple threads through XenForo's existing background processing system.

---

Features:​

• Selective Field Updates: Update only the custom fields explicitly selected by the administrator while leaving all other fields unchanged.
• Empty Fields Only: Optionally update selected fields only when their current value is empty.
• Native Field Controls: Use the appropriate XenForo input control for each custom thread field type.
• Forum Applicability: Update a custom field only when that field is available in the thread's forum.
• Native Batch Update Integration: Adds custom field controls directly to XenForo's existing batch thread update workflow.

---

Useful for:​

• Bulk Field Changes: Update custom field values across multiple threads at once.
• Forum Management: Apply consistent field values to groups of existing threads.
• Targeted Updates: Change selected fields without affecting other custom field data.
• Large Updates: Process bulk changes safely through XenForo's background job system.
