Fb optic 1870 investigation: DO NOT MERGE

[bmartel]

This pull request introduces a significant improvement to the stability of the AppStore and TabStore by adding checks for the isAlive state from the mobx-state-tree library. These changes ensure that operations are not performed on instances that have been destroyed, preventing potential runtime errors. Additionally, the isAlive check has been applied consistently across views, actions, and flows in both stores.

Stability Enhancements:

AppStore Updates:

• Added isAlive checks to computed properties like isLabeling, currentView, and dataStore to prevent accessing properties of destroyed instances. [1] [2] [3]
• Wrapped critical actions such as startPolling, setMode, and removeAction with isAlive checks to ensure they are only executed on valid instances. [1] [2]
• Updated flows like setTask, fetchProject, and fetchUsers to return early if the instance is no longer alive. [1] [2] [3]

TabStore Updates:

• Added isAlive checks to views like all, canClose, and columns to prevent returning invalid data.
• Ensured actions such as setSelected, deleteView, and addView are only executed when the instance is alive. [1] [2] [3]
• Protected flows like saveView, updateViewOrder, and duplicateView with isAlive checks to avoid modifying destroyed instances. [1] [2] [3]

These changes collectively enhance the robustness of the application by preventing operations on invalid or destroyed store instances.
