Polish editor projects and device lifecycle

[temiroff]

What changed

• refine the editor layout, light theme, canvas, headers, actions, and device cards for clearer navigation and consistent feedback
• add guided project lifecycle, artifact handling, and project-scoped deployment behavior
• add compute-device-first setup with SSH inspection, managed runtime installation, reuse/replace/side-by-side choices, progress streaming, pause/resume, uninstall, and protected credentials
• organize robots under their compute device and separate deployment-runtime status from authenticated hardware status
• add robot pause, resume, and exact-service restart controls with progress reporting and disarmed-by-default safeguards
• document the project and managed-device lifecycle

Why

The previous setup and device screens mixed compute devices, robots, and runtime state, while long-running remote actions did not provide enough feedback. Side-by-side installations also needed strict service/port isolation and lifecycle operations needed to target the correct runtime or robot service.

User impact

Users can set up a compute device, install or reuse a managed runtime, attach multiple robots, deploy workflows, inspect accurate status, and control each lifecycle stage from a more compact and consistent editor. Remote actions show progress, credentials stay transient, and robot motion remains disarmed after resume or restart.
