feat: skip properties that are considered readonly (snPosition defined)

trying to fix or skip properties in general mapped to sn positions

• setComponentInfo injects a readonly key into the property that can be used in component.py to determine if a property is readonly or not (has snPosition defined = readonly).
• HTML rendering of properties where snPosition is defined will be non-editable (meaning not even a textbox)
• additional protection on updating properties in localDB to skip updating properties that are mapped to SN positions
• recursive uploading also skips updating properties that are mapped to SN positions
