Several projects at once — and a wrong-project push that did not happen

Done: several TIA projects open at once, picked under Target. Plus browsing HMI screens and drawing LAD/FBD blocks network by network.

Then a dangerous bug showed up: after an update the projects swapped their assigned connections. A client connected to one project was suddenly talking to another — a push could have gone into the wrong project. It was caught before anything was pushed.

Fix: every project has a fixed assignment and every answer carries the project name, so the app verifies who it is talking to. Updates now also wait until all projects are idle.
