Add arch‑aware ProgramFiles folder selection to release workflow

Add a variable that chooses ProgramFilesFolder or ProgramFiles64Folder based on the
CPU architecture, replacing the hard‑coded value. Remove the obsolete
ARPINSTALLLOCATION property and correct the registry key paths in the
Wix XML. Simplify the Icon source string with interpolation.
