🔧 Fix: Keep Popover Open When Always On Top is Enabled

	•	Updated popover behavior:
	•	When alwaysOnTop is enabled, the popover behavior is now .applicationDefined instead of .transient, preventing it from closing when clicking outside.
	•	Added updatePopoverBehavior() to dynamically adjust the behavior based on alwaysOnTop.
	•	Ensured window stays on top when losing focus:
	•	applicationDidResignActive(_:) now keeps the popover open and orders it front regardless.
	•	Removed unnecessary popover.contentViewController?.view.window?.level = .floating to avoid conflicts with updateWindowLevel().
	•	Refactored AI Chat selection logic in MacMistralPopup:
	•	Simplified how initialAddress is determined from chatOptions.
	•	Ensured WebView preloads correctly before displaying UI.
	•	UI Improvements:
	•	“Always on Top” menu item state now updates dynamically.
	•	Cleaned up redundant size logic in loadView() to use a default frame.

✅ The popover now remains open when alwaysOnTop is enabled, even when the app loses focus.

Refactor popup handling and project structure in MacMistral

	•	Added PopoverManager to centralize popover handling logic.
	•	Implemented MacMistralPopup to dynamically load and manage AI chat content.
	•	Updated AppDelegate to delegate responsibilities to PopoverManager and MenuManager.
	•	Improved project organization by separating concerns into respective files.
	•	Included utility enhancements in WebViewHelper for better web session management.
