fix(db-run): use single-string ArgumentList for Cyrillic /Execute paths

Start-Process without -NoNewWindow uses ShellExecute API which corrupts
Cyrillic characters when ArgumentList is passed as an array. Switching
to a single concatenated string fixes file-not-found errors for paths
like МояОбработка.epf.
