JSON Widget Design

Goal: Beautify all JSONField displays in Django admin using django-json-widget for editable fields and a prettify_json helper for readonly fields.

---

Approach

Use django-json-widget to replace the default textarea with a collapsible, syntax-highlighted JSON editor. For readonly JSON fields, use a format_html helper that renders pretty-printed JSON in a styled <pre> block.

Scope

Editable JSON fields (get widget)

App	Model	Field
orchestration	PipelineDefinition	config, tags
orchestration	StageExecution	output_snapshot
notify	NotificationChannel	config

Readonly JSON fields (get prettify_json display)

App	Model	Field
alerts	Alert	labels, annotations, raw_payload
alerts	Incident	metadata
alerts	AlertHistory	details
checkers	CheckRun	metrics
intelligence	AnalysisRun	provider_config, recommendations

Implementation

1. Add django-json-widget to pyproject.toml and install
2. Add "django_json_widget" to INSTALLED_APPS in config/settings.py
3. Create a shared prettify_json helper in a common location
4. Apply JSONEditorWidget via formfield_overrides on admins with editable JSON fields
5. Add prettify_json readonly display methods on admins with readonly JSON fields
