Fix the ACT1Q3 status cycler callback

[w3lld1]

Summary

• I corrected ACT1Q3_Callback03_ChangedLevel to use ACT1Q3_UnitIterate_StatusCyclerEx instead of the Act 1 Quest 2 status cycler.
• This keeps the changed-level status update within the quest-specific callback identified in the issue.

Validation

• Targeted source regression check: verified the callback invokes the Act 1 Quest 3 status cycler exactly once and no longer references the Act 1 Quest 2 status cycler.
• git diff --check upstream/master...HEAD

I could not run the repository's Windows/MSVC CMake build and test matrix in this Linux environment, so I left that full build to upstream CI.

Fixes #230
