wxGUI/history: Order commands by time and optimize node refresh

[lindakarlovska]

This PR addresses several interconnected enhancements that have been linked into a single PR:

1. Command Ordering:
   Commands are now ordered from newest (at the top) to oldest. Originally, they were not sorted - there was not mechanism for that.

2. Node Refresh Optimization:

• Replaces the method _refreshTree(), which only refreshed and sorted day nodes, with _reloadNode(), which reloads and sorts both day nodes and command nodes.
• When a node is updated with new information (after a command run finishes), the update is made directly to the node's attributes. Previously, the node was removed and re-added, which caused delay. Refreshing and sorting are now made through new methods in the new HistoryTreeModel .

3. Refactoring:
   Necessary refactoring to support the changes in command ordering and optimization improvements.

It may work, but this line looks strange to me...

But otherwise it looks like it works nicely!

Well, the behavior is a bit strange here.. First I assumed that it should work without SetModel line, just:

    self._model.SortChildren(node)
    self._orig_model = copy.deepcopy(self._model)

similarly as it is in a datacatalog.
But in our case, the history tree is not loaded - just empty panel is shown .. So I tried another variant:

def _reloadNode(self, node):
    """Reload the model of a specific node"""
    self._model.SortChildren(node)
    self._orig_model = copy.deepcopy(self._model)
    if node != self._model.root:
        self.RefreshNode(node)

but the result was the same, again no error and the panel is empty.

What works is this:

   def _reloadNode(self, node):
        """Reload the model of a specific node"""
        self._model.SortChildren(node)
        self._orig_model = copy.deepcopy(self._model)
        self.SetModel(self._model)

which looks a bit better than the original method but no glory.
