🧹 Remove unused SelectFileOrDir overload

[Ven0m0]

🎯 What:
Removed the obsolete, single-parameter SelectFileOrDir(btn) function from Other/7zEmuPrepper/Final.ahk.

💡 Why:
The function SelectFileOrDir(btn) was fully superseded by a newer SelectFileOrDir(btn, *) overload later in the script that correctly handles parameter mismatches and correctly relies on y coordinate checking instead of global variable manipulation and partial hwnd indexing. Leaving the obsolete version in the script creates confusion and unnecessary code duplication.

✅ Verification:

• Analysed the single usage of SelectFileOrDir in the script, which passes (btn,*) and effectively routes to the proper SelectFileOrDir(btn, *) function.
• Performed formatting checks ensuring DOS/CRLF (unix2dos) line endings and correct UTF-8 preservation natively.
• Validated with git diff that no other logic or behavior was modified.
• Simulated repository SKILL.md tests to rule out syntax breakages.

✨ Result:
Cleaner, more maintainable code with dead code eliminated. The codebase is healthier without risking any behavior changes.

Code Review

This pull request removes a redundant and unused definition of the SelectFileOrDir function in Other/7zEmuPrepper/Final.ahk, consolidating the logic into a single simplified version that utilizes the control's Y position. I have no feedback to provide as there were no review comments.
