docs(web): expand technician guide with practical details

- Add download link + curl workaround for antivirus blocking
- Note that curl only downloads, xetup + Enter needed to run
- Split preflight checks into separate section with details
- Explain Product Key priority (OA3 > GVLK) and when to fill in
- Document config load/save buttons for per-client presets
- Add adminx9 account explanation (autologon for reboot cycle)
- Warn about Atera MFA popup during SW install
- Note that partial failures don't stop deployment - check summary
- Add troubleshooting section: Deploy.log path + local report.html
