Binding OnClick/OnRightClick to call OpenMenu() on macOS routes the menu
open through showMenu(), which runs the blocking [button mouseDown:] inside
a dispatched block on the serial main GCD queue. While the menu is open that
block never returns, starving every other main-queue task — both tray item
updates and the webview event delivery that drives React freeze until the
menu closes.
Revert to the pre-d9f0189 state: no click handlers bound, native NSStatusItem
auto-show for left-click, Wails default rightClickHandler for right-click.
refreshSessionExpiresLabel() is kept for the follow-up fix.
