feat: model attribute conditions and section conditional visibility

[ManukMinasyan]

Summary

• Model attribute conditions: visibility conditions can now reference the parent model's database columns (e.g., show field when product.type === 'physical'), not just other custom field values
• Section-level visibility: sections support the same conditional visibility system as fields, with full parity for both custom field and model attribute conditions
• Fix visibleJs/visible() conflict: server-side visible(false) was preventing visibleJs() from ever rendering, breaking reactive visibility on edit forms

Key changes

• New ConditionSource enum (CustomField / ModelAttribute)
• ModelAttributeDiscoveryService for introspecting model columns via Schema::getColumns()
• VisibilityData and CoreVisibilityLogicService accept optional ?Model $record
• FrontendVisibilityService generates $get('column') vs $get('custom_fields.code') paths per source
• SectionComponentFactory applies visibleJs without conflicting visible() for reactive visibility
• VisibilityComponent admin UI with source selector and dynamic inputs for model attributes
• Section create/edit uses slideover with larger width when SECTION_CONDITIONAL_VISIBILITY enabled

New feature flags

• MODEL_ATTRIBUTE_CONDITIONS — enables model attribute source in visibility conditions
• SECTION_CONDITIONAL_VISIBILITY — enables visibility conditions on sections

Test plan

• 415 tests passing (366 existing + 49 new)
• PHPStan clean (0 errors)
• New SectionVisibilityIntegrationTest covers:
  • SectionComponentFactory applies visibleJs without visible() (model attr, custom field, mixed)
  • Feature flag gating
  • All section types (Section, Fieldset, Headless Grid)
  • JS expression generation for all operators and logic modes
  • Livewire integration (edit page rendering with section conditions)
  • Backend evaluation (ALL/ANY logic, SHOW_WHEN/HIDE_WHEN, mixed conditions)
  • Edge cases (empty conditions, null record, multiple sections, null values)
• New ModelAttributeConditionsTest covers ConditionSource enum, ModelAttributeDiscoveryService, VisibilityData with records, mixed conditions, backward compatibility

Pull request overview

This pull request introduces two major features for conditional visibility in custom fields: model attribute conditions and section-level visibility, along with a critical fix for reactive visibility on edit forms.

Purpose: Previously, visibility conditions could only reference other custom field values. This PR extends the system to also reference the parent model's database columns (e.g., show field when product.type === 'physical'). Additionally, sections can now have the same conditional visibility as fields, and a server-side rendering bug that prevented reactive visibility has been fixed.

Changes:

• Model attribute conditions: Visibility can now reference parent model database columns via new ConditionSource enum and ModelAttributeDiscoveryService
• Section-level visibility: Full parity with field visibility including both custom field and model attribute conditions
• visibleJs/visible() conflict fix: Removed server-side visible(false) that prevented visibleJs() from rendering, enabling reactive visibility on edit forms
