Miscellenaous bug-fixes from p5 deployment

Description

This MR aims at fixing a few bugs discovered during deployment at p5. In particular:

• Fix the broken DCS exported DCS publications. They were all invalid, leading to the DCS protection system triggering and the chambers being powered off.
• Clean-up and uniformize of the GE2/1 demonstrator layout tree for easier and more consistent deployment.
• Implement a re-try for the MGT reset status checks.
• Avoid the generation of a local run number when a global run number will be provided.
• Fix the lifetime-only function manager state machine definition.
• Fix the FSM state reporting in the FEDMonitor application.
