Fix SetupWagoData nil value error by adding LibAddonProfiles safety checks

[Copilot]

This PR fixes the error attempt to call method 'SetupWagoData' (a nil value) that was preventing users from opening the Wago UI in-game.

Root Cause

The error occurred because the wagoData.lua module was failing to load when LibStub:GetLibrary("LibAddonProfiles") was called without proper error handling. If the LibAddonProfiles library wasn't available at load time, the entire module would fail to load, making the SetupWagoData function unavailable when called during initialization.

The error stack trace showed:

Interface/AddOns/WagoUI/main.lua:67: attempt to call method 'SetupWagoData' (a nil value)

Solution

Implemented a comprehensive approach to handle LibAddonProfiles dependency issues:

1. Safe Library Loading: Changed critical library imports from:

   local LAP = LibStub:GetLibrary("LibAddonProfiles")

   to:

   local LAP = LibStub and LibStub:GetLibrary("LibAddonProfiles", true)

2. Protected Method Calls: Added null checks before using LibAddonProfiles methods:

   local lap = LAP and LAP:GetModule(moduleName)

3. Function Existence Checks: Added guards before calling SetupWagoData:

   if addon.SetupWagoData then
     addon:SetupWagoData()
   end

Files Changed

• WagoUI/main.lua: Protected SetupWagoData call in init()
• WagoUI/modules/wagoData.lua: Safe library loading and method call protection
• WagoUI/wagoFrames/introFrame/directProfilesPage.lua: Protected SetupWagoData call
• WagoUI/wagoFrames/components/profileList.lua: Safe library loading
• WagoUI/wagoFrames/altFrame/altFrame.lua: Safe library loading with method protection

The fix ensures the addon gracefully handles scenarios where LibAddonProfiles is unavailable while maintaining full functionality when it is present.

Fixes #25.
