docs: update Nexus docs for Early Access release (#2339)

* docs: reframe Nexus from beta to Early Access

Shopware Nexus has moved from beta to Early Access. Update the Nexus
product docs accordingly: rename the status notice, the available-features
and limitations sections, and the getting-started prerequisites/limitations.
Feature scope and limitations are unchanged; GA remains the target milestone
for the roadmap table.

* docs: document Nexus user management, versioning, and current monitoring

Add a User Management page (Admin/Builder/Viewer roles, invitations,
per-company access) and document workflow versioning (history, compare,
restore), which has shipped. Correct the execution-monitoring section: a
per-node timeline and per-node payload inspection are now available, so the
"no per-node logs / limited payload inspection" limitations are removed.
Also surface config templates, manual run, and JSON import/export.

* docs: link the Nexus club for questions and feedback

Add a feedback callout on the Nexus overview and a pointer from
Troubleshooting to the Nexus club, where Early Access users can ask
questions and share feedback.

* docs: troubleshoot activating the Nexus ingestion service via CLI

When runtime extension management is disabled (common on composer-managed
installations), the Shopware Nexus Event Ingestion Service cannot be
activated from the Administration. Document the CLI alternative
(app:activate ShopwareNexusIngestionService), based on a merchant report.

+# User Management
+
+Nexus access is scoped to your company. Every user who belongs to the company is assigned a role that controls what they can see and do.
+
+## Roles
+
+| Role | Access |
+|------|--------|
+| Admin | Full access — can manage users, settings, and all workflows |
+| Builder | Can create and edit workflows, but cannot manage users or settings |
+| Viewer | Read-only access — can view workflows and execution results |
+
+## Managing users
+
+Admins manage users from the **User management** screen, which lists everyone in the company with their role and status (Active, Inactive, Pending).
+
+From here, an Admin can:
+
+- **Invite** a new user by email and assign an initial role
+- **Change permission** to move a user between roles
+- **Remove** a user from the company
+
+:::info
+To keep companies from being locked out, you cannot change your own role, and
+the last remaining Admin cannot be demoted.
+:::
+
+## Invitations
+
+Invited users appear as **Pending** until they accept. Admins can resend or
+revoke a pending invitation at any time. Once accepted, the user becomes Active
+with the role they were assigned.
