setup.exe exit 1603 right after removing the bundled consumer Office almost
always means the old install is pending a reboot. The script handed users a bare
1603; now it explains it. Changes:
- Test-RebootRequiredHard (CBS/WU only) GATES Reinstall-OfficeVL before the ~3 GB
download, so a pending reboot stops early with reboot+re-run guidance instead
of failing with 1603.
- Invoke-Odt failure path detects pending-reboot / 1603 and tells the user to
reboot + re-run; ships reboot status in telemetry.
- Get-OdtLogTail also searches %TEMP% (where the C2R client logs the real error)
and prefers error-bearing lines, so a failure no longer reports an empty log.
