chore(app): remove orphaned ConfigEditor page

Imported nowhere and absent from the router — an unreachable bulk-editor
superseded by the typed detail pages (ServiceDetail/ProgramDetail/
ScheduledDetail), which edit via ConfigPanel. It also called endpoints that
no longer exist (GET /components, PUT/DELETE /config/components/{name}; the
API uses /deployments and typed /config/{programs,services,jobs}/{name}).

App builds clean.
