mw4print: add -debug flag for step-by-step diagnostic logging

Browse Source 
Adds runtime diagnostic logging to track down why printing is broken.
Pass -debug (or /debug) on the command line; all output goes to
mw4print-debug.txt next to the exe (append mode, timestamped lines).
No effect on normal operation when the flag is absent.

What is logged:
- Startup: AssetsDirectory1 path and full command line
- OnCreate: DB config loaded, timer created
- DoCopyData / OnFileOpen: each file queued for printing with filename
- OnTimer: which file is being processed each second, LoadPR result
- DoPrint: nPlayers count, PrintDlg call + result (on failure logs
  CommDlgExtendedError hex code), DB export call/result, SetupFonts
  result, StartDoc result, EndDoc vs AbortDoc, final return code

The CommDlgExtendedError value on a PrintDlg failure will identify the
root cause (e.g. CDERR_NODEFAULTPRN = no default printer configured).
