Description of the Change

• Replace specialized rsvp-guest-count-input and rsvp-anonymous-checkbox blocks with flexible form-field block
• Consolidate block-specific logic into unified, configurable form field system
• GatherPress Alpha handles breaking changes in this PR Migration for anonymous and guest blocks. gatherpress-alpha#15

Block Template Updates

• Updated attending.js template to use form-field with fieldName: 'gatherpress_rsvp_guest_count'
• Updated no-status.js, waiting-list.js, and not-attending.js templates for anonymous checkbox
• Configured form-field blocks with specific attributes (fieldType, label, placeholder, etc.)

Backend Logic Refactoring

• Added handle_rsvp_form_fields() method to dynamically process form-field blocks based on fieldName
• Implemented field-specific interactivity attribute injection for guest count and anonymous fields
• Added visibility logic: hide guest count when limit is 0, hide anonymous checkbox when disabled
• Updated meta handling to properly work with boolean values for anonymous RSVP setting

Editor Integration

• Enhanced RSVP block editor to show/hide form fields based on event settings
• Added applyFormFieldVisibility() function to conditionally apply CSS classes
• Integrated guest limit and anonymous RSVP meta detection for real-time field visibility
• Fixed meta value type consistency (boolean handling)

Code Quality Improvements

• Fixed PHPStan static analysis issues (removed unreachable code, simplified logic flow)
• Resolved JavaScript linting issues (spacing, trailing commas)
• Added proper error handling and type checking
• Improved code documentation and comments

Technical Benefits

• Maintainability: Single form-field block handles multiple field types through configuration
• Flexibility: Easy to add new RSVP form fields without creating new blocks
• Consistency: Unified interactivity and visibility handling across all RSVP fields
• Performance: Reduced block registration overhead and simplified rendering logic

Backward Compatibility

• Existing RSVP functionality maintained
• No breaking changes to user-facing features
• Old block templates replaced seamlessly with new form-field configuration

Closes #1091
