Fix stuck deployment in new procedure wizard

The "Build first deployment" step in the clone-template and import wizards could spin forever even after the build finished successfully, leaving you unable to complete setup.

• Fixed the wizard hanging on the build step by ensuring live build status always reaches the page
• Added a fallback that detects a finished build within a second if a realtime update is missed
• Prevented duplicate procedures and stations from a double-click or retrying after a failed build
