fix(docker): prevent inspector from covering Logs and Exec

[JRebertt]

Summary

• close the container inspector in the same state transition that opens Logs or Exec
• share the transition handlers between row actions and inspector actions
• prevent the inspector's Docker-specific layer from covering the shared Drawer and Dialog portals

Why

The inspector uses a higher stacking layer than the shared Logs drawer and Exec dialog. Both actions mounted successfully, but Logs was fully hidden and Exec was partially covered. Removing the inspector before mounting the destination surface avoids nested overlays without changing global z-index behavior.

Tests

• npm test — 163 passed
• targeted ESLint — no errors
• npm run build — passed
• manually verified that Logs and Exec open unobstructed from the container inspector
