sync: Dataforth sync fixes, TestDataDB stability, and client scripts

Dataforth DOS:
- TestDataDB: singleton DB connection fix (crash prevention), WAL mode,
  WinSW service config, backup script, uncaught exception handlers
- Sync-FromNAS.ps1: Get-NASFileList temp file approach to avoid SSH
  stdout deadlock, *> $null output suppression, 8.3 filename filter
  for PUSH phase, backslash-escaped SCP paths, rename-to-.synced
- import.js: INSERT OR REPLACE for re-tested devices
- Full import run: 1,028,275 -> 1,632,793 records, indexes added
- Deploy script for sync fixes to AD2

Client scripts (temp/):
- BG Builders: Lesley account check, MFA phone update
- Lonestar Electrical: Kyla/Russ Google Workspace setup, 2FA bypass
- AD2 diagnostics and NAS connectivity tests

PENDING: Investigate why newest test_date is Jan 19 despite daily tests
