Three changes:
1. renderPrevCard: always render prevAsset/prevMachineInfo divs
(not conditional on GPS coordinates)
2. loadPreviousPhotos: call lookupPrevAsset for ALL photos with
machine_id, not just those with GPS coords
3. saveMachineIdInline: dynamically create asset info divs on
the card if they don't exist yet (defensive fallback)
Previously, manually entering a machine ID on a card without GPS
would silently succeed but never show the asset name/location
because the display elements only existed on GPS-equipped cards.
