debug: Add parameter debugging and remove redundant PAUSE messages

Changes:
1. Added DEBUG output at script start to show %1 and %2 parameters
2. Removed 46 redundant "ECHO Press any key..." lines before PAUSE
   - DOS 6.22 PAUSE command already displays this message
   - No need for custom echo with same text

Debug output will show:
  DEBUG: Parameter 1 = [value]
  DEBUG: Parameter 2 = [value]

This will help diagnose why machine name parameter is not being
received when running: T:\DEPLOY.BAT TS-4R

Files modified:
- DEPLOY.BAT: Added debug lines 18-22, removed 10 ECHO lines
- UPDATE.BAT: Removed 7 ECHO lines
- CTONW.BAT: Removed 8 ECHO lines
- NWTOC.BAT: Removed 6 ECHO lines
- REBOOT.BAT: Removed 4 ECHO lines
- STAGE.BAT: Removed 6 ECHO lines
- CHECKUPD.BAT: Removed 2 ECHO lines
- DOSTEST.BAT: Removed 2 ECHO lines
- AUTOEXEC.BAT: Removed 1 ECHO line

Deployed to D2TESTNAS: /data/test/DEPLOY.BAT

Next test: Run T:\DEPLOY.BAT TS-4R and check DEBUG output
