Mouse behavior improvement

When left-clicking on an errand/task location without an agent on it, deselect all selected agents and open the task dialogue (right-click opened window) for the location.

Meeting on Jul 31 suggests:
Merge the agent-related task dialogue and location-related task dialogue into one combined dialogue.

The combined dialogue has two elements:

• location-related task text box
• agent-related task text box (optional)

When right-clicking, if there's an agent, show the agent-related task text box; if no agent at the location, just show the location-related task text box in the dialogue.

@TachikakaMin, There are some visual issues with the task ID. Please check if things look unusual on your side.
In branch tym_dev_window_mac_fix, there's a fix by llm for the window pop-up issue on Mac. Please check if those are usable.
