Context menu, copy button, multi-component actions

- The 'More' menu can now be opened under the mouse, through the context menu action (right click/control-click on Mac/menu button on keyboard).
- Add copy-components button to menu.
- The menu can now be opened while multiple components are selected; if the clicked component was among the selected components, the selection will be preserved. Some menu actions--currently *copy* and *delete*, apply to all selected components. These actions will change their displayed labels when multiple components are selected. If a single-component action is executed, the component it was applied to will become the sole selection.

Fixes#11604
Most issues were caused by a problem with Project List flooding the network with its requests - this was fixed on develop.
But one assertion was flaky - it assumed we will see the "real" run result on `write` node, but sometimes it is immediately overwritten by dry run.
But the most important part of this PR is adding traces to Electron packages - it's should be much easier now to debug E2E test failures.
Also renamed the previously misnamed "E2E tests" to "[GUI] integration tests".
