Plugin TUI: Admin panel field renderer integration (Phase 8)

[hegner123]

Admin Panel Plugin Field Integration

Extends mcms-field-renderer web component to handle fields of type plugin in the admin panel.

Plan: ai/plans/plugin/PLUGIN_TUI_SCREENS.md — Phase 8

Files

• internal/admin/static/js/components/mcms-field-renderer.js

Implementation

1. Add plugin case to connectedCallback() switch
2. Inline mode: Load web component from plugin's approved HTTP route (GET /api/v1/plugins/<plugin>/interface/<interface>/component.js). Component dispatches field-change events.
3. Overlay mode: Render button with current value. On click, open <dialog> loading plugin's web UI. Committed value returned via custom event.
4. Plugin HTTP route must be approved via existing plugin route approval system

Note

Admin panel uses HTTP-served web components, NOT the coroutine bridge (TUI only).

Depends on

• Plugin TUI: Standalone screens + async data (Phases 3-4) #231 (Standalone screens + async data)
• Plugin TUI: field_plugin_config extension table (Phase 6) #233 (field_plugin_config extension table)
