Show attachment images in the operator UI

The CLI kiosk and the dashboard operator UI now support attachment images. Attach a board photo, probe shot, or failure close-up during a run and it shows inline next to the phase instead of as a bare filename, so the operator can compare it against the unit while the run is live.

• Added inline image rendering for run attachments in the CLI kiosk (served locally) and the dashboard operator UI (served after upload)
• Fixed station runs so attachment images reach the dashboard, matching OpenHTF and Robot runs
• Improved deployment history to show who ran a CLI deploy instead of "unknown"
