• Moving all configuration dialogs into top level ui components.

Summary

NIFI-15822

Adds support for viewing the read-only configuration of components in the Connector canvas, and refactors the existing flow-designer configuration dialogs into a shared, reusable location.

Read-only configuration view (Connector canvas)

• Adds a viewComponentConfiguration action and effect that opens the appropriate configuration dialog (EditProcessor, EditConnection, EditPort, EditLabel, EditProcessGroup, EditRemoteProcessGroup) in a strictly read-only mode for the Connector canvas. Permissions on the entity are forced to read-only-without-write before the dialog is opened.
• Wires the new action into the canvas via component double-click and a "View Configuration" entry in the context menu, with a Funnel guard so unsupported types are no-ops.
• Wires the dialogs in read-only mode by leaving edit-only callbacks unset (e.g. getConnectionSourceComponentId, calculateCollisionBends) and stubbing helper callbacks (createNewProperty, createNewService, convertToParameter, goToParameter, goToService) so users cannot trigger edit affordances. Each dialog component already guards against absent callbacks.

Dialog reorganization

• Moves the configuration dialog components from pages/flow-designer/ui/canvas/items/ into a shared ui/common/component-dialogs/ location so they can be consumed by both the flow designer and the connector canvas:
  • edit-connection
  • edit-port
  • edit-label
  • edit-processor
  • edit-process-group
  • edit-remote-process-group
• Decouples each promoted dialog from direct NgRx Store injections. Data flows in via @Input() observables (saving$, currentUser$, availablePrioritizers$, breadcrumbs$, propertyVerification*$, etc.) and user actions flow out via @Output() event emitters (editProcessor, editConnection, editPort, editLabel, editProcessGroup, editRemoteProcessGroup, openNewParameterContext, verify, plus the start/stop/enable/disable ComponentRequest outputs on the processor dialog).
• Promotes dialog request and update types (EditComponentDialogRequest, EditConnectionDialogRequest, UpdateComponentRequest, UpdateProcessorRequest, UpdateConnectionRequest, StartComponentRequest, StopComponentRequest, EnableComponentRequest, DisableComponentRequest) and the ConvertToParameterResponse interface to state/shared so all dialog consumers depend on canonical types rather than feature-page services.
• Removes the now-unused type re-exports from pages/flow-designer/state/flow/index.ts and pages/flow-designer/state/shared/index.ts and updates all consumers to import directly from the canonical state/shared location.

Utility extraction

• Extracts five helpers from CanvasUtils to a standalone ui/common/utils/component-state.utils.ts so the promoted dialogs do not depend on the flow-designer CanvasUtils service:
  • runnableSupportsModification
  • remoteProcessGroupSupportsModification
  • getComponentTypeForSource
  • getComponentTypeForDestination
  • getConnectableTypeForDestination
• The runnableSupportsModification and remoteProcessGroupSupportsModification helpers use optional chaining and nullish coalescing so they handle entities lacking nested status fields without throwing.
• Converts getConnectionSourceComponentId (lookup) and calculateCollisionBends (positioning) into @Input callbacks on EditConnection so the dialog no longer reaches into CanvasUtils.

Test additions

• New connector-canvas.effects.spec.ts coverage for viewComponentConfiguration$ exercising every supported component type, the read-only permission overrides, and the Funnel no-op guard.
• New component-state.utils.spec.ts (25 cases) covering all five extracted helpers including the missing-status fallback.
• New edit-process-group.component.spec.ts covering the parameter-context permission table and the visibility of the Create Parameter Context button under different currentUser.parameterContextPermissions.canWrite values.
• New edit-remote-process-group.component.spec.ts covering the relocated dialog.
• Updates to the existing flow-designer effect, controller-services, footer, graph-controls, and canvas specs to reflect the moved imports.
