📄 Description

Describe your changes

Fix a memory leak in the tray menu: every relayout built a brand-new menu tree while the replaced one was never destroyed. Wails keeps each MenuItem in a process-global map until Destroy is called, so all items of every previous tree
(labels, click closures, bitmaps, submenus) stayed reachable forever and the GUI's memory grew with every status transition, profile refresh or language change.

The fix destroys the replaced tree right after SetMenu swaps in the new one. Since the old items can now be destroyed, the Connect/Disconnect click handlers no longer capture their own menu item for the async error path; they resolve
the current item under the menu lock instead. Additionally loadProfiles now relayouts only when the profile rows actually changed, which drops the redundant full menu rebuilds (previously 2-3 per status transition, now typically 1).

Summary by CodeRabbit

Bug Fixes
- Improved tray menu reliability for connect/disconnect actions, including safer handling while the menu is being rebuilt.
- Prevented stale tray menu items from being referenced by current actions.
- Reduced unnecessary tray menu relayouts by updating profiles only when user or profile list actually changes.
- Improved tray updates when the active profile changes via background status flows.
- Fixed concurrency issues updating the session-expires tray label to avoid conflicts during menu relayouts.
