sync_intune: align Phase 3/5/6 columns; ignore benign 'Failed: 0' tails

Cosmetic + accuracy fixes spotted on the live test PC:

- Phase 3 deploy/install lines had a stray double-space after the
  checkbox; Phase 5 'Share creds present in HKLM' and Phase 6
  'Administrator renamed' had wider misalignment. All four lines
  collapsed to single-space-after-checkbox so the column lines up
  with the rest of the table.

- Phase 4 status detector was greping the last 30 lines of each
  Install-*.log for /(?i)\b(ERROR|Failed|exception)\b/. That hit
  benign summary lines like 'Failed: 0' or 'Errors:    0' and
  marked successful runs as failed (Install-VCRedists.ps1 was the
  trigger -- 8/8 'Already installed - skipping' but the summary
  contained 'Failed: 0' and Phase 4 said FAILED). Tightened the
  regex to also exclude /\b(ERROR|Failed|Failures|Errors|Exceptions?)\s*[:=]\s*0\b/
  so the keyword has to be next to a non-zero value (or the
  vocabulary 'Exit code 1603 - FAILED' style still trips correctly).
