fix: reading an unset style property returns "" per CSSOM, not undefined (#328)

* fix: reading an unset style property returns "" per CSSOM, not undefined

Reading a property that is not set — via `el.style.someProp` or
`el.style.getPropertyValue("some-prop")` — returned undefined, but CSSOM
defines both as the empty string (the property getter is routed through the
same handler as getPropertyValue). Callers that assume the spec, e.g.
`el.style.color.replaceAll(...)`, crash on the undefined. Normalize an absent
property to "" in the style getter.
