fix: find EmuDeck Windows where its scripts look

functions/all.ps1:4-14 (emudeck-we 037460ef) reads the APPDATA
settings.ps1, else the one under the profile, and takes C:\Emulation when
neither names a folder. Only the first was read and a forced platform fell
back to %USERPROFILE%\Emulation\bios. A network install names its share
through $VolName (JSONtoPS1.ps1:166-172), and a UTF-16 settings file is
decoded.
