fix: write AppleScript to temp .scpt file instead of using -e flag

The -e flag approach breaks on multi-line AppleScript and on file paths
containing spaces or quote characters. Write the script to a temp file
in os.tmpdir() and invoke osascript with the file path instead. The
temp file is cleaned up after execution.
