feat: Add UPDATE.BAT redirect to DEPLOY.BAT in proper location

Created UPDATE.BAT in test root that redirects to the correct
DEPLOY.BAT location in T:\COMMON\ProdSW\ with proper argument passing.

Changes:
- UPDATE-ROOT.BAT: New redirect file that calls DEPLOY.BAT with %1
- fix-root-bat-files.ps1: PowerShell script to deploy UPDATE.BAT and
  delete old DEPLOY.BAT from root
- Deployed UPDATE.BAT to AD2:C:\Shares\test\UPDATE.BAT (syncs to NAS)
- Deleted DEPLOY.BAT from root (only exists in COMMON\ProdSW\ now)

Usage:
  T:\UPDATE.BAT TS-4R  (calls T:\COMMON\ProdSW\DEPLOY.BAT TS-4R)

Benefits:
- Shorter path for users (T:\UPDATE.BAT vs T:\COMMON\ProdSW\DEPLOY.BAT)
- Backward compatible with old workflows
- No duplicate DEPLOY.BAT files
- Proper argument passing for machine name
