Remove inaccessible "express" feature

[GregorShear]

I anticipate revisiting this feature, and referencing this work, but for now we can remove a lot dead code

[jshearer]

Happy to merge as is, deleting code/cleaning up is always great. That being said, Claude found a few dangling threads that could net even more deletions!

Workflow store still carries express-only state

customerId, redirectUrl, and their setters (setCustomerId, setRedirectUrl) have zero remaining callers after this commit. ExpressWorkflowGuard was the only writer for both.

ui/src/stores/Workflow/types.ts

Lines 19 to 25 in 6d0f8f5

	customerId: string;
	redirectUrl: string;
	resetState: () => void;
	setCatalogName: (segments: Partial<CatalogName>) => void;
	setConnectorMetadata: (value: WorkflowState['connectorMetadata']) => void;
	setCustomerId: (value: WorkflowState['customerId']) => void;
	setRedirectUrl: (value: WorkflowState['redirectUrl']) => void;

ui/src/stores/Workflow/Store.ts

Lines 76 to 94 in 6d0f8f5

	setCustomerId: (value) => {
	set(
	produce((state: WorkflowState) => {
	state.customerId = value;
	}),
	false,
	'customer ID set'
	);
	},
	setRedirectUrl: (value) => {
	set(
	produce((state: WorkflowState) => {
	state.redirectUrl = value;
	}),
	false,
	'redirect URL set'
	);
	},

That leaves an unreachable branch in useEntityWorkflowHelpers

Since redirectUrl can never be set again, externalRedirect in HeaderLogs.tsx is always false, so the window.location.href branch in exit() can't fire for any surviving flow. HeaderLogs is the only caller that ever passes external=true.

ui/src/components/shared/Entity/HeaderLogs.tsx

Lines 23 to 31 in 6d0f8f5

	const redirectUrl = useWorkflowStore((state) => state.redirectUrl);
	const testAction =
	formStatus === FormStatus.TESTED || formStatus === FormStatus.TESTING;
	const saveAction =
	formStatus === FormStatus.SAVED || formStatus === FormStatus.SAVING;
	const externalRedirect = Boolean(saveAction && redirectUrl);

ui/src/components/shared/Entity/hooks/useEntityWorkflowHelpers.ts

Lines 87 to 109 in 6d0f8f5

	const exit: RouteHandler = useCallback(
	(customRoute?: string, external?: boolean) => {
	logRocketConsole('EntityWorkflow:exit');
	resetState();
	let route: string;
	if (!customRoute || !hasLength(customRoute)) {
	route = generatePath({ catalog_name: catalogName });
	} else {
	route = customRoute;
	}
	logRocketConsole('EntityWorkflow:exit:navigate');
	if (external && hasLength(route)) {
	window.location.href = route;
	return;
	}
	navigate(route, { replace: true });
	},
	[catalogName, generatePath, navigate, resetState]
	);

docs/STATE.md still documents the flow

ui/docs/STATE.md

Lines 100 to 107 in 6d0f8f5

	## Multi-Workflow Support
	Different entity creation/edit flows exist as separate contexts and store hydration chains:
	- `capture_create` / `capture_edit`
	- `collection_create` (transformations)
	- `express_capture_create` (simplified flow)
	- `materialization_create` / `materialization_edit`

Orphaned translation string

expressFlowIntegration had exactly one consumer, PoweredByEstuaryWatermark, which this commit deletes.
