fix(examples): use normal sign-in without environment gates

[RaychevAngel]

Summary

• Use account creation and normal CLI sign-in; introduce DispatchDesk as fictional.
• Remove temporary environment confirmation and endpoint rejection from setup and the launcher. Previous confirmation flags remain accepted but hidden for compatibility.
• Keep sign-in checks, URL hygiene, trial bounds, identity fencing, previews, receipts and uncertain-write protection.

Verification

• Default customer endpoint and no-confirmation regression tests fail before the change and pass afterward.
• Offline setup/launcher/distribution tests and deterministic archive rebuilds; no live submissions, infrastructure, billing or model changes.
• The corresponding docs use the same source bytes. A new immutable example release will replace the links, not overwrite old assets.
• Historical evidence is unchanged; this is not a claim of new Production execution proof.

Summary by CodeRabbit

• Documentation
  • Updated setup guidance to cover account creation, CLI installation, supported environments, and starting with a small trial.
  • Clarified that examples use the signed-in account and connection, and that previews should be reviewed before execution.
• Bug Fixes
  • Setup checks no longer require explicit Dev confirmation and accept valid HTTPS API endpoints, including production endpoints.
  • Authentication guidance now directs users to sign in with the CLI.
